[QUOTE="Hugnot, post: 2979248, member: 115658"] A 12 GA recoil can hurt! My Rem 870 loaded with 1 OZ 00 buck or same weight slug had recoil, but the light weight 06 hurt more. [ATTACH alt="Screenshot (824).png"]523250[/ATTACH] This is the olde kinetic energy formula E = ((m*v)^2)/2 where E is foot pounds, m = mass in slugs (gun weight in pounds/acceleration of gravity giving slugs), acceleration of gravity = 32.163 fps/fps, v = gun velocity in feet per second ^2 indicates values squared / Indicates division The gun velocity is shown by: [ATTACH alt="Screenshot (825).png"]523259[/ATTACH] The gun velocity is calculated by: Vg = ((bullet wt. * bullet velocity) +(powder wt. * gas velocity))/(gun weight in pounds * 7000) This calculates gun velocity by dividing total momentum by gun weight in grains. Just guessing that gas velocities would be less with lower pressure 12GA loads than 06 loads. [/QUOTE]
