Interesting muzzle velocities. Much faster than what I am getting out of my Tikka T3 Lite 22 inch barrel.
My T3 must have a tighter bore is all I can figure. I am only getting 2950 fps with a Sierra 130gr SPBT. using 59.3 grs of H4831.
I tried to work up to the traditional 60.0grs of H4831, and I was getting a sticky bolt lift, the ejector pic recess hole was indented on the case heads and the primers were cratered around the firing pin impact and flattened out around the rim of the primmer hole in the brass.
I figured at 2950 fps I was getting bug hole 4 shot groups at 100 meters, so I accepted that as a load and never looked back.
Good Luck,
Don
