my loads do not approach reloading book velocities?

[QUOTE="Kennibear, post: 927078, member: 51650"] If you reload pistol ammo you will find an even greater disparity between published velocity and the speed your gun generates. I find Hornady and Sierra to be closer to published and Nosler to be pretty off. The data listed on the posts here are backed up with field velocity data and so is pretty good. Too many variables to simplify this but oversize chambers and bores along with shorter barrels are probably the leading causes. I had a Form 1 M16 and a Frankenstein AR that both had 20" barrels. The AR had a match chamber that I cut myself as well as a tight bore and the F1/M16 had a Colt factory average barrel. The Frankenstein was a good 100 fps faster with everything and developed pressure signs sooner too. My middle son had a Remington 700 in 30/06 w/ 24" barrel and I have a custom Mauser 30/06 with a 27" barrel and they both posted identical velocities. His was a "fast" gun, the only one I have actually found as other 30/06's posted slower velocities with the same ammo. I have no clue as to why his 700 was so fast. Could've kicked him into next week when he sold it.... I don't chase down that "lost" velocity anymore. The loading manuals are strangled by the lawsuits and you need only read some of the 70's manuals to see how far the loads have been cut back. If you think your gun may not be cranking out the speed it should, sell it and get another. Works on cars too.... KB [/QUOTE]
