If you’re seeing ejector marks at all, you’re running hot.
All rifles are different, and in my experience, I rarely find hand loads match manual velocities. Frankly, with the exception of Weatherby ammo, factory loads have never matched advertised velocity. Of my 3 Tikkas, one requires 2.5 grains more of powder to match manual velocity. Another requires an additional requires 1.5 grains of additional powder, while a third, hits pressure 2.5grains less than manual max loads. It is true that rifles can have slow or fast barrels. I have a Sako that is really fast. My 3 Tikkas, at least with the relatively few rounds I’ve had through them clearly are not fast. Some have said they pick up velocity after a few hundred rounds..... It would be nice but I really won’t make a difference on game.
FYI, I really like the 140 AB with RL 26. The load averages just under 3200fps.
