How is rifle recoil energy calculated?

Free recoil energy = 0.5 × rifle mass × (bullet momentum + propellant gas momentum)² / rifle mass². Typical .308 Win recoil is 12–16 ft-lbs (16–22 J); .338 Lapua Magnum produces 35–45 ft-lbs (47–61 J).

Does recoil affect long-range accuracy?

Yes — high recoil increases flinch anticipation and muzzle movement before bullet exit. Rifles above 20 ft-lbs of recoil energy typically require a muzzle brake or suppressor to maintain sub-MOA precision at distance.
