If you’re shooting a particularly light or heavy firearm, you’ll need to do a separate calculation, but this will be a fair comparison of what the rifle weight normally is. Analyze over a dozen models of rifles chambered in each cartridge to determine the average rifle weight to put in the formula.Just recognize that it’s going to push you a lot–even though it won’t be painful.Ībout Backfire’s Rifle Recoil Table: How we perform calculations 50BMG usually report mild recoil similar to a.

Some people look at the recoil energy of a 50BMG and think they will be KILLED by 83.17 ft-lbs of free recoil energy however, the 50BMG is a physically heavy gun (usually over 30 lbs), so the recoil moves slowly (also because of the muzzle brake). It would hurt much more than the semi-truck. Instead, imagine a baseball traveling at 25 inches per second that hits your shoulder.
Because it’s giant and heavy, it’s going to move you significantly, but it won’t really hurt at all since it’s moving slowly. Now that truck creeps forward and pushes your shoulder at a speed of 2 inches per second. Suppose a giant, heavy semi-truck is parked in front of you with your shoulder on the bumper. This makes it tough to figure out the recoil of a rifle unless you look up a lot of other information first.Īfter shooting a lot of different rifles and cartridges, I have found that recoil velocity number accurately predicts how much pain you’ll feel, and the recoil energy predicts how much you’ll get rocked back and thrown off your target in the scope. The trouble with this formula is that most people don’t know the powder charge unless they hand load their own ammunition, and all of the other number depend on several factors. This formula relies on the formula for recoil velocity, which is simply (Bullet Weight In Grains * Muzzle Velocity in FPS + Powder Charge in Grains * Muzzle Velocity * 1.75)/(7000 * Rifle Weight in Pounds). The formula for determining the free recoil energy of a firearm is (Rifle Weight in Pounds/64.34) *(Recoil Velocity in FPS^2). Without further ado, I give you… the rifle recoil database! Cartridge I do NOT recommend muzzle brakes for youth shooters because the loudness scares them more than the recoil–even with hearing protection on.
As you read through the table, remember you can pick a much heavier-hitting cartridge if you’ll be using a muzzle device. Keep in mind that attaching a muzzle brake reduces the free recoil energy by about 40% and attaching a suppressor reduces free recoil energy by about 32%.
Over 15 ft-lbs – Begins to be very difficult to spot the bullet impact on target through the scope because of the recoil.Over 25 ft-lbs – In a lightweight rifle, even experienced shooters can struggle to shoot more than 15 rounds without pain or developing a flinch, UNLESS a muzzle brake, suppressor, or heavier rifle is used.Over 30 ft-lbs – Massive recoil that can be difficult for even seasoned shooters to shoot accurately.Selecting a rifle and cartridge combination which does not produce too much recoil for the shooters is critical to being able to shoot accurately without developing a flinch.Ī Quick Guide to Understanding Free Recoil Energy Recoil is measured by free recoil energy, and recoil velocity. It is commonly called a gun’s “kick.” More recoil is created when more powerful powder loads and lighter-weight firearms are used.
Recoil is the force of a gun pushing back against the shooter when a bullet is fired. I created it because other recoil databases I found online are dated and do not have the depth of research to truly compare cartridges apples-to-apples.įor those of you who are new to firearms, let’s discuss the basics of what recoil is before we look at the data. I have spent literally hundreds of hours collecting the information in this blog post.
