Earlier in the week I posted the thread on Keyholed Targets. I called Bersa and described the problem on 11/30, and on 12/2 a new barrel arrives. I call that great customer service!
Haven't concluded that this has fixed the total problem but it certainly is an improvement. At the range shooting at 50 ft, USA reloaded ammo shot better with only 1 turned bullet out of 10. I then shot 50 Federal rounds with no turned bullets; on Sunday some of the Federal's were turning. One thing I did discover is that this gun loves 147 grain bullets. Problem is the cost!
Again, thanks for the advice and suggestions as I worked through this.
