New Barrel Trouble - Help! - 03/29/21 12:52 PM
I recently installed a new Shilen Select Match barrel on my Savage 10 BA Stealth (6.5 CM, 1-8", 4 groove, ratchet rifling). So far I've run about 85 rounds through it and it groups really well. The first 10 were to break it in cleaning to bare metal after each shot.
I've been doing some load development and this weekend I ran 2-10 round ladder tests at 400 yds with some IMR 4451 I bought from Chad which went fine. After the ladders, I was shooting a 5 round group and the 4th round wouldn't chamber and neither would any of the remaining unfired rounds. Fired and unfired brass would chamber just fine. I brought it home and scoped it and found very heavy copper in the throat and also what looks like pieces of lead.
Its interesting that the groups did not deteriorate and 3 rounds just prior to the malfunction went into 1.3” at 400 yds (.31 MOA)
Something doesn’t seem right. What could be causing this? How should I remove the Copper/lead in the throat? Should I call Shilen or just clean it and try again?
