Shooting a 6.5 Creedmoor, Proof 24" SS barrel. I have noticed during the last few matches I have shot that a pattern has emerged with each target getting a little worse when comparing group size. Normally shoot between 30-40 rounds per match. Four rounds of 5 shots for score.
Yesterday the match conditions were a little tough and I shot more sighter rounds than normal. We shot 2 rounds of 10 for score unlimited sighters 1000 yds. First round I shot 10-12 rounds to sight in and to confirm accuracy to qualify for the match then 10 shots for score. Not a great target but about 1 moa. In the next round first round is on the sighter plate second shot to confirm is off the plate. I shot 10 shots to bring it in and confirm but seemed to be all over the place. Shot my 10 rounds for score and the target went to 2 moa. Total rounds fired 47. During this second round I was also experiencing some hard bolt action but then it cleared up. ??
You can save the "shooter sucks" comments if you want because I have already confirmed that issue is real. But if you need to throw them in I understand.
I have know for a while that this barrel does not like being dirty but assumed that it was more like 70-100 rounds now I think the barrel may be losing accuracy between 20-30 shots. I haven't tested this yet as a controlled test and here is the question. What yardage would you test your accuracy at? My first thought is 300 since I would see some impact separation and not as much wind effect.
Does anyone think it's odd that a barrel would start to open up that bad after 20 rounds? I know each one is different.
