Last night I shot a 5 round group at 100yd and verified my zero was on. Group was about .75", maybe a touch smaller. I then shot groups at 225, 333, 433, and 545. The groups were all very similar at 2-3'. But each had one flyer that was low right of the group by almost 2 moa. The 545 group was 3 rounds in about 1.5" with two rounds as flyers. The barrel (Savage 7mm-08) has quite a few rounds through it.....but I have no clue how many. 1500+ would be a good guess. I know I am the weak link in my system....but I feel like I was breaking good clean shots. What are symptoms of the barrel being shot out.
