If youve paid attention, that is 5cm at 500m, also known as one click on a mil/mil scope with .1 clicks. The heavier the bullet and the faster it moves, the higher its muzzle energy. 1. . Do not touch that elevation dial. As I learned at Pecos this year, a 10% difference in score is the difference between placing where Tyler placed (in the top 10) and where I placed (somewhere a good bit lower than top 10). Those were the CCI 40-grain Polymer Coated Clean-22 and the Eley 38-grain Subsonic Hollow Point . So for existing firearms, longer barrels equal higher muzzle velocity and therefore increased muzzle energy. The Federal Ballistics Calculator lets you quickly determine the trajectory for any rifle or handgun load, and save data for an unlimited number of loads. You saved a ton of ammo - now is the time to use it, when you have great . I have five, all read differently by 100s of fps. I supposed someone could put the numbers in Excel and the program would "calculate" the #'s for you basically by just doing the math. Dont do that. One thing Ill unhappily confirm: chronos are a pain and not reliable. The Train and the Defend ammunition produces the exact same muzzle energy and velocity. The standard deviation (aka "SD") is a measurement that shows how much variation from the average number exists in a sample. How fast a bullet is traveling when it leaves the end of a gun's barrel, called the muzzle velocity, is of great interest to both those who work in the field of ballistics and physics students looking to cover a few key concepts in one, well, shot. Get out that barely-relevant copy of The Ultimate Sniper and hope that it holds the answers. QuickLOAD software is an internal ballistics package that will allow you to estimate muzzle velocity and a whole host of other things (like chamber pressure and barrel time) based on detailed inputs (powder, charge, case dimensions, bullet dimensions, etc.). Chronographs can be had for around $100 and they definitely have their place. Removing margin of error is preferable to claiming superiority based on simplicity. a gun image by timur1970 from Fotolia.com. Just enter bullet weight and velocity, and this handy foot pounds of energy calculator will return a muzzle energy value, in foot-pounds of energy. \begin{aligned} &x = x_0 + v_xt \;\text{(constant v)} \\ &y = y_0 + \frac{1}{2}(v_{0y} + v_y)t \\ &v_y = v_{0y}-gt \\ &y = y_0 + v_{0y}t-\frac{1}{2}gt^2 \\ &v_y^2 = v_{0y}^2-2g(y-y_0)\end{aligned}, Georgia State University Hyperphysics: Trajectories, University of Utah Medical School: Firearms Tutorial, University of Alaska at Fairbanks: Projectile Motion. Its just uncomfortable for people who live in the past. BUT, if you triple the velocity you get 9 times the energy due to the V being squared in the energy formula! We thought you might enjoy it as well. Five hundred meters? It is paramount to calculate the correct muzzle velocity and to use the appropriate ammunition for the firearm, in order to maximize the accuracy . To get to 300m, I need hold 2 mil below my 100m zero. CD = 7 feet. This is repeated in Winchester's Power Max cartridges. Ive found that it is very rare for the hottest load of any cartridge to be also the most accurate. I have a responsibility to this site to tell the truth about guns, and sir, the truth is I wont write what I truly feel about you because I wont stoop to the strata you occupy. Drop - The vertical position of the ball, in inches, at that distance. Enjoy! For the record, the bullet is the 150 grain Federal Fusion. Or momentum. If your memory is a little off you may take a pencil and a notebook but leave your calculator at home . Im in West Michigan, so my typical elevation is about 670 feet above sea level. If you know the acceleration of the bullet, you can determine muzzle velocity from the kinematics equation. This is a useful measurement in that you can use it to compare power settings of an airgun, the energy . The calculator allows for plasticity of data across a full spectrum of environmental conditions. Math is irrefutable and forces you to accept facts.

gtag('config', 'UA-86427305-5'); A simple, easy to use muzzle energy calculator to find out foot pounds of energy of a projectile. You should say fk it and go buy one today. Is there a calculator out there somewhere on the interseine for estimating black powder velocities? This counter-intuitive property of motion rears its head repeatedly in projectile-motion problems. Ill tell you one thing . Granted you can shoot 20 rounds to walk that 13 308 into the target at a mile and hit all day long, but i found my 20 375CT with better BC and higher MV makes it much easier. Wind is different across the entire trajectorys height and range yet we can only eyeball the mirage and get one data point at the kestrel. Distance from measurement point to muzzle (yards), Ballistic coefficient (G1) under standard conditions, Free recoil energy of the firearm (ft-lb), Barometric Pressure: 750 mm Hg = 29.53 inches Hg. And Im trying to figure out how/whether the ballistics you generate are correct regardless (wrong MV, wrong bc, correct drops), which must be true since it works. Im shooting .308 Winchester out of a 26 inch barrel (but that is immaterial). Weight. Our free Ballistic Calculator generates thousands of shot simulations using your provided load, muzzle velocity, and real-world environmental conditions to create the most accurate bullet drop compensation data available. Diameter (inches) Weight (grains) Firearm. Two of the loads were subsonic with muzzle velocity a little over 1000 feet per second. We use this nifty bullet energy calculator when we chronograph projectiles. The CVA Accura V2 Long Range muzzleloader is the top of the line model from CVA and has been rated the best long-range muzzleloader from Muzzle-Loaders.com. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . Thanks for the disadvice but the point of the question is as stated, whether or not someone had created a program yet for plugging in ball diameter, powder charge, barrel length and any other data points. That last number is a constant created by multiplying two times the acceleration of gravity by 7,000 - the number of grains in a pound. If you have any question or need help with your account, you may contact us to assist you. That carries ~400fps over your 13.5 configuration. There is nothing to look at except for the last yard line. But precision is not equal to accuracy. Ive been on enough hunts to know it doesnt really matter in real life. In a self-defense situation, things tend to happen faster. We find it highly valuable and worth the price. Just to be a problem, Ill do 2300fps. Its all relative, people. Stopping the attacker is far more important than killing him. Ballistic specifications for specific cartridges are based on measurements from tests performed using SAAMI specifications. Stop it. Since we saw the impact at 4.5 or so, we hold the 4 mil line on your target center. Modified Point Mass Trajectory Calculates a trajectory from bullet dimensions. the muzzle). Use the calculator below to calculate the kinetic energy of a bullet. After you make those shots, drive down and put markers or draw visible indicators over your bullet holes, which are certainly (or should be) directly under your target center. Align the 4 mil line with the center and observe where your impacts are. where v 0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. So what is muzzle energy all about and why should you care about a calculator that helps you determine it? While this seems logical when you look at the numbers, the reality is very different. This will make the feel and point-of-aim comparable. I agree with your short&thick=rigidity=PRECISION. Every fanboy seems to want to throw in humidity and Coriolis like theyre trying to impress someone, but it matters so little in real life at realistic ranges that its just safe to set it at 50 percent all the time. I found this information on a 3X5 card in my notes. But, if you refuse to acknowledge our 2A is put in there against tyranny, which exactly means when the gobbermint use goons in blue and green who do not know better to oppress the citizenry, i dunno what truth about guns you have to offer. Not sure how well he did but hes got some amazing skills. Fire. The goal of an armed citizen is to stop an attacker as quickly as possible. Muzzle Velocity and Down-Range Velocity If youve hit a deer, you can give him ample time to lay down and bleed, tracking a blood trail as necessary. What? You need to pay attention to velocity in two aspects, and they are: RIFLE BALLISTICS. Consistency builds confidence and confidence builds consistency. When talking about bullet kinetic energy, the word muzzle energy is often brought up. An old black powder gunsmith in NC gave this to me 30 years ago: And after everything is done based on using information gathered in Zonie's post and you have gone to one of the Black powder loading manuals that has tables of velocity information for similar rifles, you. You make note of it, hold with the start of the duplex, so 3 mils, on the target center and fire a few more times. Choose one of these pre-filled forms to get started. All these fancy things are there to make that first shot and every shot better. You still dont know jack at the end of the procedure. A decent high power rifle with a quality barrel , I enjoy my Noreen BN 36 for 500 yarders . It allows you to estimate velocity based on your current zero and the amount of drop at another chosen range, say 300 yards. Calculate Muzzle Velocity from Instrumental Velocity. [emailprotected] Bullet Energy . Crumpled ? Our projectile motion calculator is a tool that helps you analyze parabolic projectile motion. The Impact Ballistic program allows to you to match your specific cartridge to any of the TRACT riflescope reticles, providing BDC (Bullet Drop Compensation) for long range accuracy and precision in a simple and easy-to-use online program. If you click one of these links before you buy, we get a small commission while you pay nothing extra. This is something that is known as muzzle velocity, and it is a very important factor in determining which bullet cartridges will give their best performance at any given distance based on their weight and speed.. Even better. If you can stretch your memory back to high school science, you should remember that kinetic energy is the energy of motion. Examine the problem to find the displacement of the object and its initial velocity. Make note of this. Based on the fact that there arenttoo many velocities that will get your given bullet from A to B and put them all in the same place, you are then able to do the last and most critical part of this whole process. Muzzle Velocity. For my abilities and shooting the El-Cheap-o rifle I am, I think its excellent. However, that doesnt mean real science and math werent used to come up with these numbers. Also, Microsoft Paint. Many gun people will even use the term interchangeably with stopping power. But is muzzle energy important? That 46 inches is nothing in real life. TOF - Time of flight (how long (in seconds) the bullet is in the air). Chances are good that youve had to follow a blood trail before recovering game. You have entered an incorrect email address! Its a game when its on paper for score, not life and death. CONNECT WITH US What would YOU DO if an Airsoft Ref came up to you like this? You can measure this with a chronograph, or look it up in a reloading manual (feet per second). So, your practice shooting will be similar to what you will experience if you fire your weapon in a defensive situation. I have a real-world rifle for real-world uses and it still does .1mil at 100m all the way to 1000m and Ive used it on animals and targets alike without issue. Deer, pigs, and coyotes all drop just the same from 100m to 500m+. In fact, the faster an object is moving, the more kinetic energy it has. Bullet or shot weight (gr) 1 oz = 437.5 gr. Set max as your actual max, so 500m for me. Worry not, friend, I wont come out empty-handed. Select a bullet from the list or enter in the properties below. Your chronograph is most likely the problem , there is no way youre getting 500fps diffs with the same powder and loads on the same bullet . Group size at 100 yards is just under half an inch in both directions (horizontal/vertical), so I say its half an inch. Your 308 load moves approx 46 more at 1000 yards than my .260 load in a 10 mph wind. Getting ones load standard deviation down into single digits of fps is challenging, but it can be done. A low number indicates most numbers are close to the average. ), FFP mil/mil scopes can be had for under $700 from SWFA and US Optics makes affordable scopes under $2000. The Federal 115-grain 9mm ammo has a muzzle velocity of 1,180 fps, while the larger bullet is propelled at 1,000 fps. Inconsistent muzzle velocity results in vertical stringing. I HATE MATH !!!!!!! Then. To learn more about how we use cookies, please review our ProChromo, CEDM2, Magnetospeed, Superchrono (measures from sonic boom), and Labradar. Our calculator creates a proper ballistics trajectory chart that details range, drop, velocity, energy (fps), wind drift, and time. I figure that is to much deviation if I have been careful reloading, 168gr bullet at 2400 fps? Blackhorn 209 posts 1,900 fps of muzzle velocity for 100 gr. It doesn't have any major disadvantages in velocity and is still overall quite maneuverable. Now you know you have a bullet that impacts 5.1 mils low at 500m. Best barrel length for 5.56mm (and .223 Remington) depends on your use case. Go back to the line and look through your scope. It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. If I was having a rifle built it would wear a 22 barrel, and experience shows I would still be carrying a nearly 300fps advantage over a 13.5 barrel. Its all broken down into tens. inches. Pure math, man. If an object is moving, it has kinetic energy. grains. What about it? Dont believe me? Thats .1 mil at that distance, which makes 1 mil equal to 50cm. There isnt anything a 13 .308 cant do. So, as the title says, how does one go about figuring things out with only five shots? Next Post . It will change, so leave it on one setting for this procedure. You will learn more than I have time to write on this page. What's A Typical .308 Winchester Muzzle Velocity. Nielsen Specialty Ammo makes custom slugs for airguns including Airforce Airguns, American Air Arms, Daystate, FX, Edgun and most brands of quality air rifles. Theres a lot going on with ammunition. The 300 Blackout's .30 caliber bullet can be made especially long, and as the result may weigh up to 220 grains quadruple the weight of the typical 223 Rem round's. So heavy a bullet conveys a subsonic muzzle velocity and correspondingly softer report. Tell me thats not important. The ballistic performances for the 7mm-08 Remington based off a 24 inch test barrel on two grain types for muzzle velocity are 2,800 ft/s (140 gr Nosler P), 2,650 ft/s (150 gr Speer HC-SP). The energy in Winchester Train rounds is sufficient to take down a threat in most defensive situations, the problem is where the energy goes. (Notoriously enough, I do most of my shooting and hunting with a 13.5 .308.) Watch where it impacts next to the target. I consider long range in the field to be 500m and out. Converting an AR-15 to fire 300 Blackout is as simple as swapping its barrel. This is useful for comparing handloads, muzzle . So what? Those centimeters are what you want. The equation used is: vnew = mknownv2 known mnew v n e w = m k n o w n v k n o w n 2 m n e w. Where the variables are as follows: vnew v n e w. the new bullet's velocity (what we want to compute) Its at 4.6, so a half mil high. Since the AR-15 rifle is such a highly customizable gun, there are various features you can change which impact muzzle velocity, and we'll examine them below. Firing under anything other than Standard Metro conditions changes the effective ballistic coefficient of the projectile (from Sierras 6th Ed). MOA is kind of a bitch system since there are various MOA versions. Never go full metric. With that bullet, at 2000 fps you will never be more than an inch low or high in a 100 yard shot. I've found many "tables" to range from poor to worthless. Muzzle 25 50 75 100 125 150 175 200 225 250 Velocity (fps) 1900 1843 1787 1732 1679 1628 1579 1531 1484 1439 1395 Kinetic Energy (ft lb) 1723 . I forgot to mention that I also have shot .300 BLK out to long ranges and found the hits to be easy to make. For an overall great rifle, there's nothing wrong with the most popular barrel length of 16 inches. To use the calculator, simply fill in the input values (blank white boxes) in the large black box. Remember, it isnt about speed or barrel length. Abstract. + .7 inches at 50 yards, 0 at 100 yards, -4 inches at 150, and -12.1 at 200. You may add items to the list on the right in order to create a bar graph comparing the different items. What youll need is ; Instead, it is a rather ethereal figure that can only be computed using the previously mentioned formula. In this guide, well examine why muzzle velocity is important and how you can use it to be a more effective hunter and more prepared self-defense shooter. Kestrel 5700 Ballistics Weather Meter with Hornady 4DOF. The real variable in long range shooting is wind, nothing helps you negate its effects better than a high BC bullet with good speed. Of course a chronograph is the only way to get. The gun shoots, period. A ballistics calculator, primarily for round ball ammunition used in muzzleloading arms. Just checked 1 difference on .204 32g .206bc @ 1000y is 9. RL-19 for the 30-06 and IMR 4064 for the 308 no Varget I have been able to find around here. How do I use the ballistics calculator? Skip down and change the units to mil in the first column and to centimeters @100m in the second one. More about Kevin and links to his professional work can be found at www.kemibe.com. When you're ready, click calculate to generate your custom ballistics chart. It is by no means a calculator, as it uses averages and gives ballpark figures. If you aren't given the value of the acceleration but instead know the firing pressure inside the barrel, a muzzle velocity formula can be derived from the relationships between net force F (mass times acceleration), area A, mass m, pressure P (force divided by area) and acceleration a (force divided by mass). In the next set of inputs, dont really mess with most of that. Range (yards) Range Velocity Damage Penetration Power Drop Time of Flight; 0 y: 0.00 fps: Well, I hate to break it to you, but math is shooting and a calculator is more important than nearly any tool at our disposal these days, right behind a progressive mindset. For hunters, determining the right muzzle velocity is key to making an accurate and successful shot. Doesnt this mean your method of attaining MV may yeild a wrong value for MV? Because we don't know it is 2400 yet, we enter 2500 first. Go to the next section and enter atmospherics. Save my name, email, and website in this browser for the next time I comment. ALL RIGHTS RESERVED. Posts: 6834. Muzzle Velocity Calculator Ballistics Calculators Diameter (in) Weight (gr) Ballistic Coefficient (G1) Sectional density = 0.226. Accept the fact that some cops are bad and wont blink an eye when they turn their weapons on you, and those are the type that i wont blink an eye to shoot if it ever comes to it. For me, they are at 5.1 mils low of a 100m zero at 500m. 2. The latter is the way to go, but even there I get funny results maybe errors on my part in recording exactly what load Im shooting, but it happens a lot. Its the same projectile, but the speed it travels greatly affects the energy it carries at impact. Now for some constructive criticism. Mine is averaged at 29.92. I disregard any reading that is more than 10% out from what I would expect. The more complicated answer: Muzzle energy is the measure of kinetic energy a projectile carries when it . The muzzle velocity of the bullet. It . Multiply the product of the weight of the pellet (in grains) times the square of the velocity and divide that number by 450240. Our Friends So no matter how fast a bullet is fired, it is falling toward Earth just as quickly as if it had been simply dropped from your hand. The Accura LR boasts a 300-yard shooting capability by providing better velocity through its 30" Nitride-treated Bergara barrel. Yeah, this method is sort of a way to reverse-engineer your velocity. Formerly with ScienceBlogs.com and the editor of "Run Strong," he has written for Runner's World, Men's Fitness, Competitor, and a variety of other publications. Enjoyed your enthusiasm . Once the bullet exits the barrel, the gases dissipate, pressure drops, and air resistance begins to slow the bullet. Ballistics Calculator. For guys who dont have first focal plane mil/mil scopes, the going is a bit tougher because you have no clear demarcations on your crosshairs and no ability to easily gather information. Enter the actual temperature of the day. the figures were 1,187 fps and 1,331 fps. Yes. Data stays the same. Black Powder Shotguns Are Freaking Sweet! I dont ever worry about expansion rates and such. Typical handguns have muzzle velocities in the range of 1,000 ft/s, which means that such a bullet would travel a mile in a little over five seconds if it hit nothing or did not fall to the ground by that point. 7.
