The calculation goes like this (the units of measurement don't matter as long as they are used consistently): Bullet momentum: 9.5 x 840 = 8,000 (rounded). Propellant gas momentum: 3.0 x 1,200 = 3,600. So the total recoil momentum is 8,000 + 3,600 = 11,600, of which the gas produces 3,600 / 11,600 x 100 = 31%
