a gun image by timur1970 from Fotolia.com. Dont touch your elevation knob no matter what range youre shooting. This is repeated in Winchester's Power Max cartridges. But I can sorta verify bcs by measuring at the muzzle and downrange (Superchrono downrange) and calculating from those values. The Recoil velocity of a gun calculator computes the velocity at which a gun will move in the opposite direction in relation to the projectile that it fired. Amer. With 21 grs. The free recoil energy is the work that must be done to control the firearm upon firing. Keep it simple. Velocity is heavily determined by the length of the AR-15's barrel. 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. For an overall great rifle, there's nothing wrong with the most popular barrel length of 16 inches. Thanks for the article. A decent high power rifle with a quality barrel , I enjoy my Noreen BN 36 for 500 yarders . HANDGUN BALLISTICS. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . Anyway, thanks for writing this, I would like to see more posts on long range shooting. trajectory information for 100, 150, 200 yds would be an interval of 50. Nielsen Specialty Ammo makes custom slugs for airguns including Airforce Airguns, American Air Arms, Daystate, FX, Edgun and most brands of quality air rifles. lb Muzzle Velocity ft/sec. I have five, all read differently by 100s of fps. On your calculator, enter the following, being sure to enter the parentheses " ( )" characters in the equation. Brought to you by Sciencing. Tarkov Ballistics Calculator. T/C Shockwave lists a ballistic coefficient of .240 for a 250 gr. Or momentum. *yikes* hope no one paid money for this advice. The average muzzle velocity of a .308 Winchester round is around 2750 fps (feet per second). . The future and the technology in it isnt scary. Deer, pigs, and coyotes all drop just the same from 100m to 500m+. Just to be a problem, Ill do 2300fps. Start by entering your specific environmental factors and constraints as well as your ammunition and firearm details into the the calculator form. If you havent picked up on it already,Im a mil man. It is paramount to calculate the correct muzzle velocity and to use the appropriate ammunition for the firearm, in order to maximize the accuracy . They are focused on PRS competition, which is fine, but there so few actual competitors in that that they may just write it up on Olympic biathlon. To convert from ft/s to m/s, divide by 3.28. Look it up. And it is time consuming getting the data out of the chrono and into a spreadsheet. The problem is very similar to taking a compression check on an automobile engine to see if the piston rings and valves are sealing the cylinder well. Once you've completed the form click the calculate button to generate your ballistic compensation drop chart. The OP is asking about internal ballistics of black powder and round projectiles. Lets say it works out to be 3 mils at full magnification. The gun shoots, period. Your browser's Javascript functionality is turned off. I was kidding. 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. The muzzle velocity algorithm uses the known barrel length, the time the projectile 410 travels down the barrel (event E), and the calculated ammunition powder burn rate to calculate a value for the projectile muzzle velocity. The heavier the bullet and the faster it moves, the higher its muzzle energy. Once a baseline is established, you can alter it at will to match your conditions. 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 . In fact, math is in virtually every angle of shooting. Enter 100m as zero distance. I actually dont like shooting past 500m these days. Five hundred meters? If the mass m and muzzle velocity v of a bullet are known, its kinetic energy and momentum can be determined from the relationships Ek = (1/2)mv2 and momentum p = mv. The .308 doesnt peter out at long range. Long range on the target line starts at 600m. Just checked 1 difference on .204 32g .206bc @ 1000y is 9. Go back to the range or set your cell phone down and set up a target at a random distance300 yards900whatever. The folks at Precision Rifle Blog did a How much does it matter? series, and extrapolating their work from that, a 400fps advantage translates into a roughly 12% increase in hit probability (assuming identical conditions and shooter ability). Youll NB if you read these tables what Im saying is true it is very infrequent for the hottest load that Lyman has tested to also be the most accurate. In the case of a gun, the bullet replaces the piston in the cylinder . You cant avoid it. Thats a 40% decrease in effective range. Your group sizes can open up. Joined: Fri Nov 30, 2012 6:25 pm. . Neither does energy. Its easy to understand why we get so deep into the numbers. Were at 5.6, so too slow. BOOK VALUE for 2F, 24-inch barrel at 80 grains is 1560 FPS. Previous Post. You already know that you have 3 mils to the dot. Def.) Big secret: humidityhas no valid bearing on real shooting. As the bullet travels down the barrel, propellant gases build pressure and accelerate the forward motion of the projectile. You will learn more than I have time to write on this page. Can we really live without pissing off everyone else at the range while we set up a chronograph and force them all to hold fire so we can stand in front of the line? Since Im struggling as it is to keep this whole yards and meters thing straight, Im just going to go full metric. 00:02 12:50. Get the very best gear you can afford and make the most out of each shot. The firearm generates a muzzle energy of approximately 130 ft lbs of energy at the muzzle whereas that of the air rifle is only about 26 ft lbs. 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. Hopefully this proves useful! More INSANE Airsoft Gameplay from my first time at Code Red. I push 2815 fps with a similar load to the one you mentioned out of my 26 308 (disclaimer on that in a second). Well Josh , Ill try to save you a lot of trouble here and it wont take a lot of charts and fancy $2,000.00 scopes and any math . It's not perfect but it will get you much better results than this simple calculator. You have entered an incorrect email address! For example, if you double the velocity of a projectile, the muzzle energy doesnt just double, it quadruples. This number can be used to get a rough idea of a rounds destructive potential. Ive had access to literally any gun of my choice regardless of price over the years. Use the calculator below to calculate the kinetic energy of a bullet. Because we don't know it is 2400 yet, we enter 2500 first. These numbers only indicate projectile performance as it leaves the muzzle. To calculate recoil energy: Obtain the momentum of the bullet by multiplying the mass and velocity of the projectile fired. But bolt gun? Unlike other chris, my eyes glazed over. It allows you to estimate velocity based on your current zero and the amount of drop at another chosen range, say 300 yards. A large target , painted flat white rigid cardboard or plywood , about 4 x 8 . Ive always thought velocity had to be consistent to have decent accuracy, but my empirical evidence says this is not true. Pure math, man. Big deal right? Muzzle energy is the energy of a bullet right when it leaves the firearms barrel. Data stays the same. This calculator is a simple estimator. 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. It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. 3. Just give it a good estimate and call it good. Now, I'm not saying Lymans data is right but I've fired a lot of shots out of a .50 caliber TC using a 80 grain 2Fg powder load and they always "crack" when their shot. The more complicated answer: Muzzle energy is the measure of kinetic energy a projectile carries when it exits a firearm. I figure that is to much deviation if I have been careful reloading, 168gr bullet at 2400 fps? Great read, where in West Michigan is there a 500 meter range? Good for you, bruh, because its party time. By using these equations, you can determine the path of a fired bullet and even correct for drop due to gravity when aiming at a distant target. FPS calc. Sure you want a hard-hitting round to ensure adequate energy transfer and penetration, but you also need to consider bullet design. Take the mystery and uncertainty of long-range shooting out of the equation with Impact! Muzzle Velocity (fps) Ballistic Coefficient. AR-15 Barrel Length Velocity Chart. So it comes down to what you want to do. Facebook Doing this saves you having to goof around firing at every individual range. Take that meter stick and make lines on your target. Okay, so technically your gun now has two known zero points. I never hunt with regular hunting bullets. 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. Ive been hunting with Hornady 168 HPBT match bullets for years and Ive never had an issue. Im about to save lots of TTAG readers the trouble of this labor intensive method of reverse engineering your velocity with a yardstick and a huge poster board. Its all relative, people. ; Add both the resultants and divide them with the mass of the firearm in grams to get velocity of the firearm. You can hover over the question mark icon on any field to learn more about how that field will impact your calculation. The website will also let you include a zero at Point Blank Range, which is great for guys with the duplex reticles. Ooooook, Yeah, but you get much more use out of high quality glass than a chronograph that will wind up shot, sooner rather than later. I may try switching to H4350 where I was using H414. That load produces 2400fps from a 13.5 barrel. (Feet Per . We had three high velocity loads that measured close to 1300 feet per second - The 40-grain copper plated round nose version of the CCI Mini-Mag , the 40 . To put that into perspective, I would need to step up to a 300win mag to gain a similar advantage to my current setup. ; Find the square of the velocity of the firearm. It carries no practical penalty for me because I mainly bring it out when I will be hunting from a fixed location. You may add items to the list on the right in order to create a bar graph comparing the different items. I hear you F-Class guys and this isnt for you! When you start talking about 200-400fps though, yes, velocity absolutely matters.

gtag('config', 'UA-86427305-5'); A simple, easy to use muzzle energy calculator to find out foot pounds of energy of a projectile. Removing margin of error is preferable to claiming superiority based on simplicity. 7. One thing Ill unhappily confirm: chronos are a pain and not reliable. Hell understand when you tell him how productive it will make you. 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. This calculator will display the foot pounds of energy, and help you compare the power of different loads. Lyman found that barrel and load would give about 1573 fps muzzle velocity. grains. Heres where it gets interesting. I would like to shoot longer ranges, but I only have about 300 yards at the longest. One of the downsides to using a ballistic calculator is the before vs. after effect. It is also the energy that the shooter absorbs through recoil by shooting. You now have a range card that you can go in and edit at will tailored to your individual rifle. 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.). Lord, that .06 is gonna kill us. Firearm Setup. EDUCATION 101. For me, they are at 5.1 mils low of a 100m zero at 500m. Those centimeters are what you want. Is that bullet even moving? Those were the CCI 40-grain Polymer Coated Clean-22 and the Eley 38-grain Subsonic Hollow Point . Its far more complicated than high school math, even if that sometimes feels like the most complicated thing on planet Earth. This is a useful measurement in that you can use it to compare power settings of an airgun, the energy . What We Use However, death can take anywhere from 10 seconds to a full hour depending on how fast they bleed. What about it? Humidity can be simply set at 50 percent. It doesn't have any major disadvantages in velocity and is still overall quite maneuverable. The kinetic energy of the bullet is the energy that is transferred to the target when hit. If you buy a Lyman reloading manual, youll see that they call out an accuracy load as well as a maximum load in their tables. I like the consistency of the .308 myself, but it definitely peters out at long range. For a game animal or a human attacker to die, there must be sufficient blood loss, usually through significant damage to the vascular system or a major blood-bearing organ. What should come first:consistency. We use this nifty bullet energy calculator when we chronograph projectiles. No amount of calculation is completely accurate. However, that doesnt mean real science and math werent used to come up with these numbers. See the Resources for an online tool that allows for the input of very granular information about specific firearms and bullets to achieve estimates of muzzle velocity and other data related to ballistics. 1. Thanks. Assume 100 yard zero. The heavier the bullet and the faster it moves, the higher its muzzle energy. When your rounds go trans-sonic (ie, from super-sonic to sub-sonic) on the way to the target, they can become upset and unstable, depending on bullet weight, form, etc. It can find the time of flight, but also the components of velocity, the range of the projectile, and the maximum height of flight. As gun people, we often become obsessed with ballistic data, particularly with energy and velocity. 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. Max Range. All these fancy things are there to make that first shot and every shot better. Mils are stoopid. Click Here to open in small window. Make sure its actually zeroed, because you will need it to be precise for the next part. Do not do that. Notify me of follow-up comments by email. By default, we only need four values to give you a good idea of how your shot will behave: target range, bullet weight, muzzle velocity, and ballistic . The .308 is good to a mile. function gtag(){dataLayer.push(arguments);} Click calculate, this will show you under Results 2 the aproximate Muzzle Velocity in FPS and Meters Per Second and Range in Feet and Meters for your Airsoft Gun. Range (yards) Range Velocity Damage Penetration Power Drop Time of Flight; 0 y: 0.00 fps: Now for some constructive criticism. Getting ones load standard deviation down into single digits of fps is challenging, but it can be done.

Muzzle Velocity Calculator Ballistics Calculators Diameter (in) Weight (gr) Ballistic Coefficient (G1) Sectional density = 0.226. Yes. Unless youre in a competition like that, the 6XC and like calibers dont hold up against things like the .308 for real use on game. I had not thought much about that before. Its all broken down into tens. You are trued - easy day! Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? I dont ever worry about expansion rates and such. Be safe, have fun, and enjoy! Let MV = The Muzzle Velocity calculated from the Chronograph Velocity. Here's how to do it. Effects of Barometeric Pressure, Temperature and Altitude. Yes, but you're going to need to get your wallet out. What would you consider the max hunting / target range of your platform? While this seems logical when you look at the numbers, the reality is very different. Although shooters often argue over how much energy transfer actually matters, in a self defense situation that energy dump could be what stops a perpetrator. Re: Muzzle velocity and barrel length. You may not have mils, but you do have a Sharpie. In a nutshell, a heavy bullet traveling at a slower speed is going to . Befire anything you are a private citizen paying tax to keep the system alive, and your life and family are worth more than whatever uniform youre wearing. And even when there is, the vast majority of cops and servicemen will stand with us, not some politician like king obama. Save that information. Data entry. Black Powder Shotguns Are Freaking Sweet! 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. Its just uncomfortable for people who live in the past. Projectile motion definition. Thats how velocity affects muzzle energy. Contact Us. The email address you entered is not valid. Trust me when I say that Ive been teaching people for years and this method is what I use to instruct at the range. 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. . Most of you have missed more shots than youve made, except that one time you lucked out and actually hit that pop can that somebody else left on the target rail on the 300 yard line of your local range. 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. Best Overall Barrel Length for 5.56 NATO. [emailprotected] Fire. Definitions. RL-19 for the 30-06 and IMR 4064 for the 308 no Varget I have been able to find around here. Next enter min and max range. Ah, 2400. Breath deep , exhale , and walk em in and write em down . Go buy Magpuls Art of the Precision Rifle. Wind is different across the entire trajectory . MOA is kind of a bitch system since there are various MOA versions. CD = 7 feet. Converting an AR-15 to fire 300 Blackout is as simple as swapping its barrel. Something about lots of spectators makes my finger jump . To use the calculator, simply fill in the input values (blank white boxes) in the large black box. As always, its important to remember that at the end of the day there is no substitution for accuracy. Ill tell you one thing . Go back and change that variable. If you are shooting at 500m, make the lines 5cm apart. Gun publications and avid shooters can run on endlessly about the energy of certain cartridges and even specific brands of cartridges. The value of the stability calculator is more in comparing different combinations with each other (twist rate, bullet to be used, muzzle velocity, environmental conditions, etc.)
