I removed the black donut from the extractor spring and attempted to chamber a round again with the extractor reinstalled using just the extra power spring and standard black spring insert.
I had to push it a pit to get it to chamber, round hung in chamber, extractor not letting go.
Tried the extractor spring and the insert the rifle came with, same results, round hung in chamber, extractor nor releasing the case rim.
Brass used in the test was full length sized, trimmed to length, camphered and deburred. Case length empty, 1.0690, no additional steps were taken with the brass.
Is the extractor pushing the brass into the chamber befor it clicks over the rim?
Thanks to Commander Faschisto, Pitted Bore, Hoot and Wildcatter for all your help with this.
Some times the extractor rides up on the rim ever so slightly even though the hook is past it. This causes the outside of the extractor to bind against the barrel extension. The fix is simply relieving a small amount of the extractor shank right behind the hook, so that it rides a small amount lower. I seem to recall someone else experiencing this and Wildcatter walked him through the solution. I you were using .284 Win brass, I'd expect that problem, but not Hornady 450 Bushmaster brass, with it's smaller diameter rim.
Do you envision what I'm referring to with the extractor? Once the hook passes the rim and drops into the extraction groove, the rim rides on the extractor shank just behind it. you just need to relieve the shank a small amount with a stone. Some times, just polishing it on a wheel will suffice. I'm assuming the height of the hook is not too great and it is never getting past the rim and dropping into the extraction groove.
