Barrel wear and tear

[Alan]

Accuracy loss can look quite different depending on whether you're dealing with pistol or rifle barrels. When did you start seeing a decrease in each, and what signs made you aware of it?

My bolt gun began to lose its accuracy after roughly 2600rds. The group sizes shifted from 0.7 MOA to a consistent 1.8 MOA, which shows some clear barrel degradation. I’ve never really worried about pistol barrels. They do wear down but not enough to impact combat accuracy.

With rifles, I noticed the accuracy would start to drop off after a few thousand rounds, and the groups would slowly get bigger. It's harder to tell with pistols. The first thing I usually see is that the shots aren't hitting the same spot anymore, instead of obvious wear and tear.
