I have 28 or so rounds down the pipe in a factory 6.5prc savage tactical. First couple shots hovered 2950....by the end of those first 12 shots it was 2922 (magneto speed)57.7 h1000
Pressure wasnt a problem at all so i bumped to 58.4 first 2 were back up to 2950. By the time i was finished with 16 rounds (pre filled at home/bullets seated at range) the gun had stepped down and hoovered at 2895ish.
I am seated very close to the lands. i have usually had bullets speed up as barrels get shot for the first while. So is this slow down mabey from the throat being worn in and reducing the pressure a bit?

Its shooting great with no indication of pressure yet. The last slower groups were 1/2 moa ish but now i gotta get another bump in pixie dust to get it tword the 2950 im hopeing for.
