The rifle that is 5th from the right is the 308 Win. M1 that is the subject of this thread. It is also pictured in profile two pics down.

The 4th from the right is the rifle I shoot in the Rifleman's Weekend matches annually in GA. (largest JCG match outside of Perry and the CMP East/West Games)
It has a layer of Hawkeye shooting adhesive built up on the butt plate which at that angle makes it look like there's no trap door. The adhesive keeps the butt from slipping off your shoulder in rapid fire. Old High Power shooters trick.

When you "Peened" the last 1/3 of the splines do you use a socket or a brass punch? Or do you use the ball of the machinist hammer?

I worry, and perhaps unfounded of bending or tweaking the barrel...but I supposed a wood block is a good enough back up.

I use the small hammer pictured and just tap on the edges of the spline with the flat face of the hammer. Nothing heavy handed. You only need to displace a small amount of the spline edge to tighten the fit. If overdone, you have to beat too hard on the gas cylinder to drive it into place.

OK, this thread is not getting as much "airplay" as the trigger thread, and that's a shame because it's just as important if not moreso. A few members have replied that they have, or will use this info to improve their M1. It's been 2-1/2 years since the last post, so those that have applied the techniques herein, sound off and tell us about your results.
For those that haven't seen it, the Games matches are coming up. You have time to use this to your benefit and maybe bring home a trinket or two.
