I agree with a lot that has been said concerning age of the shooter, stock fit and attitude but especially weight of a gun for a given caliber effecting recoil. I have not had the opportunity to shot any .40 or above nitro guns. I can shoot a .358 Norma or .375 HH with 300gr bullets off the bench all day with a 9lb gun.
7 drams is where I draw the line to shoot off the bench with black. I don't have trouble with 8drs and a 950gr bullet in a 13lb gun and am able to reaquire the target quickly. Shooting 10 or 11 drams behind a 1250gr bullet in a 16lb gun takes a greater level of concentration and mindset and there are days I am up for it and days I am not. Like many of the other posts I never remember recoil when shooting in the field.
