From the Hodgdon 2004 reloading manual [ I'm not going to quote all the info, it would take too long ]- " Unfortunately, too many shooters think that pressure has an effect on recoil. In truth, it doesn't. It is not included in the formula for calculating recoil as noted in our example." The only items used in their formula was the weight of shot,wad,powder,the gun and muzzle velocity- no where is psi mentioned. JDW, it looks like you are actually wrong one time. Sorry. Paul
