custom aqautics, you are basing those velocities off a caparison between a bolt and a semi, in a bolt action almost all pressure is directed towards forcing the bullet out of the barrel, in a semi part of that pressure is necessary to cycle the bolt and robs a great deal of pressure, also, M1s have to have lower pressure ammunition to avoid damaging their operating rods meaning that a springfield or other bolt action rifle would have significantly higher velocity over an M1 and if you were to compare a springfield to an SVT40 then the velocity differences would be several hundred FPS in favor of the 06.
