I have heard many people say that when you shoot a rifle from the bench it should recoil straight back and not have the muzzle "jump". I find that this is true when I shoot heavy or small bore rifles such as a .243. But when I shoot my 7mm rem mag with a pencil thin barrel the barrel of the rifle almost always jumps in the air. Is the rifle supposed to come straight back or is this just taboo? Thanks for clearing this up.
