I have something going on that I can’t figure out.
Fired this bbl for the first time just before the KY challenge last yr.
It is a 45 and shoots exceptionally well.
I set it up with a new die, got it sighted in, shot a couple matches and hunted with it last fall.
Here’s what is happening. When it was brand new I could shoot it a few shots, put it away for a few days then reload it effortlessly when I was ready to shoot again.
Last yr at the Challenge I fired a couple rds on Friday then shot the entire match on Saturday. I never cleaned it or ran a patch through it.
All was well for approximately 150 rds or so on the bbl.
I normally clean after 25-30 rds or more often as conditions require.
The bbl now has a few hundred rds on it. It’s still very accurate but now after only a few rds it tightens up until I cannot push a bullet down it.
Nothing has been changed. The die has never been adjusted , same lot of powder, primers and bullets as I started with.
I have a Hawkeye borescope and there’s nothing in the bore that I can detect.
Am I missing something? Has anyone else had a similar experience?
Thanks ahead for ur input.
