Rifle Recoil Chart: 48 Cartridges at One Declared Weight, Then Solved for Yours

Every figure below sits on this declared condition. It is the same rig used across the rest of the site, and it is the only reason these tables can be read against one another.

• ▸Centrefire rifle: 8.00 lb as-fired — receiver, barrel, optic, mount, sling and a loaded magazine on the gun.
• ▸Handgun: 32.0 oz as-fired with a loaded magazine.
• ▸Atmosphere: 59°F, 29.92 inHg station pressure, sea level.
• ▸Powder-gas velocity convention: 4,700 fps for centrefire rifle, 1,700 fps for handgun.
• ▸Muzzle velocity: taken at the barrel length printed inside the row, not at an undeclared test barrel.
• ▸Powder charge: given its own column, because on a 5.56 load it accounts for about 41 percent of the recoil impulse and leaving it out is exactly how tables end up wrong.

The arithmetic is standard closed-form free recoil. Recoil momentum equals bullet weight times muzzle velocity, plus powder charge times the gas constant, all divided by 7,000 to get out of grains. Divide that by firearm weight for recoil velocity in fps. Energy is one-half m v squared with g taken as 32.174 ft/s². Impulse is momentum divided by the same g.

Free recoil ignores stock geometry, recoil pad thickness, buttplate area, comb height, how hard you are loading the rifle into your shoulder, and whether a gas system is bleeding some of that impulse sideways and late. It is a comparison instrument. It does not predict what your shoulder feels, and anybody telling you a recoil chart predicts felt recoil is selling you something.

Sorted low to high so the ladder reads straight down. Charge weights are mid-range published loads rather than maximum — if you handload hotter than these, recoil climbs faster than velocity does, which is the trade nobody prints on the box.

Handguns get a different gas constant. A 4-inch barrel does not accelerate propellant gas anything like a 24-inch one does, and applying the rifle figure of 4,700 fps to .45 ACP inflates the answer by roughly 18 percent. That single unstated choice is why handgun recoil tables scatter so badly.

One thing worth noticing before you leave this table. 9mm 147 gr shows more recoil energy than 9mm 115 gr despite being slower, because momentum tracks the product of mass and velocity while energy tracks velocity squared — and the heavier bullet wins the momentum argument. Shooters who describe 147 gr as softer are describing a longer, slower push, not a smaller one. The impulse column agrees with them; the energy column does not.

Feed it bullet weight in grains, powder charge in grains, muzzle velocity in fps and firearm weight in pounds. It returns recoil energy in ft-lb, recoil velocity in fps and recoil impulse in lb-s.

Weigh the gun the way you shoot it. Optic on, mount on, magazine loaded, sling attached, suppressor fitted if you run one. A bare 16-inch AR-15 upper and lower comes in around 6.3 lb; the same rifle with a 12 oz optic, a 20 oz can, a sling and 30 rounds of 5.56 is nearer 9.4 lb. That is a 33 percent swing, and it moves recoil energy by a quarter.

Worked example. A 16-inch AR-15 in 5.56, scoped and loaded, hangs at 8.6 lb on a luggage scale. M193 is 55 gr over roughly 25.5 gr of powder at about 3,100 fps from that barrel. Bullet momentum is 55 × 3,100 = 170,500. Gas momentum is 25.5 × 4,700 = 119,850. Add them, divide by 7,000, and you have 41.48 lb·ft/s. Divide by 8.6 lb: recoil velocity 4.82 fps. Energy 3.11 ft-lb. Impulse 1.29 lb-s.

Look at the split in that example. The powder gas contributes 119,850 of 290,350 — about 41 percent of the total impulse. On a .308 Win 168 gr load it is 31 percent. On .45 ACP it is 5 percent. That is why the gas constant argument matters enormously for small-bore rifle cartridges with big charges and barely at all for large-bore handgun rounds, and why a recoil table that omits charge weight is guessing at nearly half the answer for 5.56.

Add a pound to an 8.00 lb rifle and you shed about 11 percent of the recoil energy. Take a pound off and you add about 14 percent. A lightweight build and a heavy-barrel precision build in the same chambering are not the same rifle to shoot, and the gap is bigger than most component upgrades will ever deliver.

Impulse is absent from that table on purpose. It does not change. A 12 lb .308 and a 6 lb .308 both deliver 2.87 lb-s to your shoulder — the heavy one just delivers it more slowly, over a longer push, which accounts for most of why it feels civilised. Weight buys you a gentler delivery of the same shove. It does not buy you a smaller one.

That distinction has a practical consequence. Adding weight helps a shooter who flinches at sharpness. It does very little for a competitor whose problem is getting the sights back on target inside a quarter of a second, because that is governed by impulse and by where the muzzle device sends the gas. Different problem, different lever.

Recoil energy in ft-lb is the number to use when you are ranking cartridges or deciding what a new shooter can handle without building a flinch. It scales with the square of recoil velocity, so it exaggerates the gap between mild and stout cartridges — which, for the purposes of choosing a first centrefire rifle, is a feature rather than a fault.

Recoil velocity in fps is the underrated one. It is how fast the gun is travelling backwards when it meets your shoulder, and it is the best single predictor of scope-eye risk and of whether a rifle will hurt on the bench. Anything above about 15 fps deserves respect and a decent pad. Above 20 fps you should be thinking about stock fit before you think about anything else.

Recoil impulse in lb-s is the number for competitors and for anyone evaluating muzzle devices. It is conserved: the total momentum that has to go somewhere. A brake reduces impulse by redirecting propellant gas rearward, and the percentage it removes from impulse is the honest measure of what it does. Energy figures make the same device look about twice as effective, which is precisely why device makers print energy.

Pick one and stay with it for the whole comparison. Half the arguments about recoil on the internet are two people quoting different units at each other without either one saying which.

Undeclared firearm weight is the big one, and it is unfixable from the outside. A table quoting .30-06 at 20 ft-lb assumed something around 9 lb; one quoting 25 assumed nearer 7.2 lb. Neither is wrong. Neither is comparable to the other.

The gas constant is the second problem, and it is invisible even to careful readers. Some sources use 4,000 fps for rifle powder gas, some use 4,700, some use 1.75 times muzzle velocity. Run M193 through the 4,000 fps version and you get 2.94 ft-lb instead of 3.34 — a 12 percent difference produced entirely by a modelling choice nobody printed. The gap widens with charge-to-bullet ratio, so it hits 5.56 and the fast .22 centrefires hardest.

Subsonic loads break the constant outright. A 220 gr .300 BLK subsonic load burns about 9.5 gr of powder and exits at 1,010 fps; assuming that gas leaves at 4,700 fps is physically silly, and it inflates the answer by roughly 15 percent. The 2.8 ft-lb printed in the table above is the conventional figure. The velocity-proportional model gives closer to 2.4. Both appear in the wild, neither is labelled, and this is the sort of thing worth knowing before you argue about it in a forum thread.

Then there is the semi-auto problem. Free recoil assumes a rigid gun. A gas gun spreads its impulse across two events — the initial push and the carrier hitting the back of the buffer tube — which is why a gas-operated .308 feels softer than a bolt gun of identical weight firing identical ammunition, even though the arithmetic says they are the same. No closed-form recoil equation models that. Anyone claiming otherwise has curve-fitted something.

In descending order of how much difference they make, and roughly in ascending order of cost.

• ▸Firearm weight. Cheapest and most reliable. Going from 7.0 to 9.0 lb cuts recoil energy by 22 percent on any chambering, and a steel weight in the buttstock costs almost nothing.
• ▸Load selection inside the chambering. A 150 gr .308 at 2,820 fps and a 168 gr at 2,650 fps differ by 4 percent in energy, but a reduced 125 gr load can drop you by a third within the same rifle.
• ▸Muzzle device. A well-designed multi-port brake removes 25 to 35 percent of the impulse at this reference rig, which reads as 44 to 58 percent of the energy. It also makes you the least popular person on the firing line.
• ▸Stock fit and pad. Contributes nothing to the free-recoil figure and an enormous amount to what you actually feel. A properly fitted comb stops the rifle rotating into your cheekbone, which is where most of the perceived unpleasantness comes from.
• ▸Gas system tuning on a semi-auto. Moves the timing and the second impulse rather than the total, so it changes felt recoil without changing a single number in these tables.

Notice that only one of those five appears anywhere in the free-recoil arithmetic. That is the honest limit of this page: it tells you what the cartridge is doing, precisely and comparably, and it says nothing whatsoever about how the rifle is set up to hand that to you. Both matter. Only one of them can be tabulated.
