Dropped in to 25 yds and 50 gr T7 PRB, shot that for a bit just to check grouping then increased incrementally to 75 gr and back out to 50 yds. (OK, there were a few at 100gr just for kicks, actually felt recoil was very slight compared to both my Hawkens)

The grouping at 75gr was a bit tighter than at 50gr; not much difference due to yardage but tighter overall compared to my first few sessions. I tried this because shooting at 80 yds w/ 70-80 gr T7 I was having quite a few fliers if I did not swab every couple shots. I should mention that in my most recent sessions I swabbed every 5 shots.
So,having never owned a new, or in this case NOS, rifle before I can only assume that this is the break-in period? I planned to allow 100 rds or so before filing the front sight; at this point I'm @ 60.

Seem normal?
