cw i would think the same, but this one fits more solid than the factory 45-70 barrel. is it possible to be too tight?
doc, i will try the winchesters. i will reload for this one if i can get it to function properly.
what's up with the round dropping in so deep past the ejector? normal? my other barrels are extractor.
The issue is as you say, its perfectly fine with two other barrels. That leaves only two possibilities.... Ammo or barrel.
Try Docs suggestion, It is quite possible that the primers in the stuff you first shot where very hard.
Slam fires are a consideration in full auto AR/M firearms, so some DO HAVE hard primers. CCI makes a 223 spec primer for just this issue.
The ETX power springs I mentioned are made by Wolffe and something a number if us do "just because"
