[QUOTE="bailey1474, post: 92915, member: 3249"] [ QUOTE ] I'm not sure what the actual velocity difference would be, but yes, if one guy free recoils a rifle and another holds it firm against his shoulder, there will be a difference in the distribution of the cartridge's energy. In the free recoil situation, some of the energy of the burning powder is going into pushing the rifle backwards, and this leaves less energy to propel the bullet forward. [/ QUOTE ] I'm not trying to be a smart *** or anything here, but this is just not true. The energy is distributed the same everytime. It's just a matter of whether or not there is a shoulder there to absorb the rearward motion. It's a matter of physics. The energy is the same everytime. I think the reason you guys are saying that the velocity will change is due to the magnum effect exhibited when you free recoil large caliber rifles. A person who shoots a large caliber rifle free recoil will shoot higher @ long range due to the muzzle jump. Someone who holds hard against the rifle will absorb some of this energy and get less muzzle jump, causing a lower POI. It has nothing to do w/more or less velocity. Just my thoughts. B.J. [/QUOTE]
