Semi-Auto Muzzle Velocity
I remember reading or hearing that for gas powered semi-autos you should expect muzzle velocity to be 100fps slower than published velocities. Is that correct? Specifically, I'm talking about a Remington 742 in 30/06 (22" barrel). The factory loads state 2810fps as the muzzle velocity but I'm thinking that I might as well subtract 100fps due to the semi-auto action plus another 50-100fps since the claimed velocity is probably high (based on a 24-26" barrel, perfect temperature, and just a liberal claim in general). Does that sound about right?

I would say 100 - 150 fps is a safe drop in velocity. Thats what I see with a 22" 7400.

I'veheard conflicting stories on this but have never actually attempted to measure the differences myself.
Anyone have any hard evidence out there one way or the other?
