You want the specs of these two loads to match. Inconsistent muzzle velocity results in vertical stringing. | 115gr | 1140 fps | 332 |, Thanks again for using our free muzzle energy calculator tool. Yes. Select a scope to prefill the following data attributes or enter your own values. 5.1 again, but the hard way. Ive found it to be very consistent. 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.. Im in West Michigan, so my typical elevation is about 670 feet above sea level. Since we saw the impact at 4.5 or so, we hold the 4 mil line on your target center. gave figures of 1,227 fps and 1,380 fps respectively. The UK legal limit for Rifles is 12 ft/lbs and for Pistols is 6 ft/lbs. Bison Ballistics Munitions, LLC This is why velocity and energy generated at the muzzle will be the greatest over the course of the bullet travel path. In addition, the muzzle velocity also affects the projectile's trajectory and terminal velocity. Drift - The horizontal drift from a cross wind. And have fun! 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 . yards. On your calculator, enter the following, being sure to enter the parentheses " ( )" characters in the equation. Enjoyed your enthusiasm . It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. I've found many "tables" to range from poor to worthless. Keep it consistent and youre golden. False. At 2400fps, my bullet makes one hole at 100m and .1 mil accuracy out to 1000m.

Actually, for me, nothing is quick at the range. That happens to be the longest distance at my local range. You can have a super-fast load and have it be not-so-great. Winchesters Train and Defend line makes a perfect example. Pure math, man. Nielsen Specialty Ammo makes custom slugs for airguns including Airforce Airguns, American Air Arms, Daystate, FX, Edgun and most brands of quality air rifles. Here we specifically present the form these equations take in the case of projectile motion. Ive found that speed isnt key to accuracy at practical ranges.. I consider long range in the field to be 500m and out. Note that these equations are independent of mass and do not take into account air resistance, a common qualification in simple physics calculations. No apologies, and youre welcome. I like the consistency of the .308 myself, but it definitely peters out at long range. The Pressure value used for each caliber happens to be the maximum SAAMI safe chamber pressure. A simple, easy to use muzzle energy calculator to find out foot pounds of energy of a projectile. With the muzzle velocity calculation function, the bullet velocity V measured at a distance of x meters/yards can be converted to the bullet velocity V at the muzzle of the barrel (at 0 m/yds). Fire again twice. 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. Help me identify this beautiful flintlock rifle, please. It allows you to estimate velocity based on your current zero and the amount of drop at another chosen range, say 300 yards. 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. The estimator uses a modified form of the Powley Ballistic Calculator. There you have it. Look it up. You will learn more than I have time to write on this page. You are trued - easy day! While a good indicator of raw performance, it only gives the consumer a vague idea of how effective that ammunition will be. The following improvements will be made: Please sign up for our newsletter so that you can be alerted the moment these new features are launched! The function is only intended for short distances, less than (or maximum) 25 m/yds. All the ballistics from all manufacturers, finally in one place. If youre really careful, you can actually take that permanent marker and draw mils on your glass. 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) Hopefully this proves useful! Muzzle energy is the amount of energy a bullet carries right out of the barrel. Here's how to do it. You may add items to the list on the right in order to create a bar graph comparing the different items. I really love what my stubby barrels are doing for me. Input the ballistic parameters of your bullet, shoot at chosen yardage, and measure the difference in drop in inches, minutes, or mrads, and hit a button. 4350 is good powder. Better put on your shades while reading this because your future is about to get bright. Once a baseline is established, you can alter it at will to match your conditions. What about it? Impractical range begins at 1000. You need to pay attention to velocity in two aspects, and they are: I have been fortunate, for the two main loads I shoot in this rifle I have found good accuracy nodes on the higher end of velocities, but without having to run at max charges or push pressures. We use cookies to improve your browsing experience. Then you drove down and check. Trust me when I say that Ive been teaching people for years and this method is what I use to instruct at the range. In fact, the faster an object is moving, the more kinetic energy it has. But bolt gun? 1. Notify me of follow-up comments by email. Even within AR-15s, muzzle velocity might be very different from gun to gun. I guess I am going to be the guy that gets bunched up on your velocity/caliber claim. If you'd like to learn more about each of the specific environmental factors, check out our list of frequently asked questions. Buy Strelok. The calculated \(v_{new}\) should turn out to be 2,669. Generally a good idea to avoid speaking in absolutes, on top of that, categorically stating that velocity doesnt matter is a bit misleading. Is it actual MOA, like 1.06 at 100 yards or is it 1? All projectile-motion problems are free-fall problems, because after an initial velocity is given to the projectile at time t = 0 of the problem, the only force acting on the projectile is gravity. It can find the time of flight, but also the components of velocity, the range of the projectile, and the maximum height of flight. For self-defense shooters, knowing the muzzle energy of your practice ammunition and your personal protection loads is important. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont.

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. Yes, but you're going to need to get your wallet out. Josh- Two things puzzle me. Wait. Do that at any range you have and then print off your data. The free recoil energy is the work that must be done to control the firearm upon firing. However, its nice to have solid data when youre scrolling through a website trying to choose the best ammunition option; Its hard to argue with numbers, after all. The next step is to look for targets that are half the distance of your truing distance. The bullet is whats true. Sure enough, you have holes at 2.1 mils. I HATE MATH !!!!!!! Even if a cartridge generates 1000 foot pounds of energy, not all of that energy is used to push the target. 7. For an overall great rifle, there's nothing wrong with the most popular barrel length of 16 inches. Then enter the bullet weight of the bullet whose velocity you want to estimate. Ive done similar work before with the JBM site. Using the function: How to use the Range Calculator. What youll need is ; We appreciate all of your support and use of our site. Fire. Bullet Energy . Now, if I drop muzzle velocity to 2400fps that brings minimum expansion range all the way in to ~325 yds. The energy in Winchester Train rounds is sufficient to take down a threat in most defensive situations, the problem is where the energy goes. Youll discover that you will certainly want a temp-stable powder like Varget. Your point A is 100m, but your 500m point B isnt your expected 5.1. Once the bullet exits the barrel, the gases dissipate, pressure drops, and air resistance begins to slow the bullet. bullet. Its easy to understand why we get so deep into the numbers. CD = 7 feet. Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? .. Also, you say twist direction and rate are important but sight height isnt. Comments like this are why people dont like this community. The website will also let you include a zero at Point Blank Range, which is great for guys with the duplex reticles. Enter 100m as zero distance. Enter the Energy (Joule) results from the FPS and Velocity calculator in the "Input 2" field along with your BB weight in grams. Also, Microsoft Paint. If you are chasing that last 25-50fps out of a given rifle/load at the expense of dangerous pressures, decreased brass life , and especially when that extra velocity might take you off the accuracy node of your barrel, then yes velocity doesnt matter. 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. This Airgun Energy Calculator is a simple widget designed to take the velocity of a projectile (bb, pellet, dart or bullet), its weight in grains, and calculate the foot pounds of energy (fpe) at the muzzle. There will be some variance, but we can work with that. Bullet Energy Calculator. And you can do it in only a few shots. Doing this saves you having to goof around firing at every individual range. You already know that you have 3 mils to the dot. How do I use the ballistics calculator? Before that, Id interpolate ballistics tables in the back of reloading books. We have better things now and these advanced optics and rifles will become the overwhelming standard in the next few years. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . You can hover over the question mark icon on any field to learn more about how that field will impact your calculation. Remember, it isnt about speed or barrel length. Ive always thought velocity had to be consistent to have decent accuracy, but my empirical evidence says this is not true. I shoot way too many different rifles and loads, so having a good bc and mv, when I can get them, might be quicker than even your method. Data stays the same. A large target , painted flat white rigid cardboard or plywood , about 4 x 8 . Because velocity has such a huge impact on muzzle energy, anything that affects velocity also affects energy exponentially. Muzzle Velocity. The modifications permit estimates for less than nominal full loads and . (Thats 10cm at 1000m for those of you that measure in Freedom Units only.) 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. 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. Max Range. Interval: Output solution distance i.e. 6. Its fun to see, but isnt practical. function gtag(){dataLayer.push(arguments);} Enter a BC and matching drag function, or select a bullet from the library and then enter the following variables: Muzzle Velocity. Now that you know thats 3 mils, hold those 3 above the target and off to the side. For self-defense and hunting ammunition, muzzle energy is just part of the equation. Align the 4 mil line with the center and observe where your impacts are. BOOK VALUE for 2F, 24-inch barrel at 80 grains is 1560 FPS. If you can stretch your memory back to high school science, you should remember that kinetic energy is the energy of motion. . All of these will lead to inaccuracy in the ballistics solution and the best way to compensate right off the bat is more velocity. Lord, that .06 is gonna kill us. . What would YOU DO if an Airsoft Ref came up to you like this? 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. Ahh, the science of walking it in and then running calculations backward. Im shooting .308 Winchester out of a 26 inch barrel (but that is immaterial). Then. For my abilities and shooting the El-Cheap-o rifle I am, I think its excellent. You'll need to Sign In or create a Ballistix Account if you'd like save your calculation data. I find I get my best prone and offhand done at that distance. By the way to prolong the service life of you brain by preventing overheating just buy MagnetoSpeed. 1000 is an imaginary landmark in rifle accuracy. An important factor in any calculation of muzzle velocity is going to be the energy output - power - whatever you want to call it - of the powder you are using. Plus, Id never shoot an animal at that range and on targets it doesnt matter. (I saidfive shots is in the title, but you can shoot more if you want.) T/C Shockwave lists a ballistic coefficient of .240 for a 250 gr. G1 Ballistic Coefficient Must be between 0.001 and 1.0. When talking about bullet kinetic energy, the word muzzle energy is often brought up.

Calculate Muzzle Velocity from Instrumental Velocity. If you havent picked up on it already,Im a mil man. Even better. Tell me thats not important. When you have it zeroed, find the longest distance you can possibly fire at. They are about like guys in F Class. Muzzle velocity and energy are often stamped right on ammo packaging. 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. You'll need only three added pieces of information [3] for your situation: Bullet weight, New charge weight, New Barrel Length. Calculating Muzzle Velocity and Trajectory With Five Shots (Or So). Gyroscopic stability Sg means the ability of a rotating object to resist the change of its rotating axis. Its about building a range card based on data. Fact is, my method works and offers the flexibility that modern people need when shooting for score or in the field. With 21 grs. A lot can happen between the muzzle and target impact. Its far more complicated than high school math, even if that sometimes feels like the most complicated thing on planet Earth. As gun people, we often become obsessed with ballistic data, particularly with energy and velocity. Your browser's Javascript functionality is turned off. (Feet Per . Change barometric pressure or temperature and all that work is for naught. Mils are stoopid. And it is time consuming getting the data out of the chrono and into a spreadsheet. Use the calculator below to calculate the kinetic energy of a bullet. 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. Do not touch that elevation dial. Count the number of mils to the wide part of your duplex and make note of it. Your 308 load moves approx 46 more at 1000 yards than my .260 load in a 10 mph wind.
