So, the issue I’ve been having Is the longer 147 grain rounds hitting the bottom of the feed cone hard enough to Deform the bullet and press it back into the case. I suspect this could have to do with how quickly the bolt is cycling and whether the 147 gr. rounds have enough energy to push the bolt back its full range.
So, did test pushing a round into the chamber at multiple angles and didn’t feel any catching or resistance. I Went ahead an polished the feedcone more so it feels very slick.
I also switched to a Sprinco red spring and headed to the range. The pistol ran with no issues and fed 5 rounds of 147 Ranger just fine. The recoil impulse felt good. It didn’t feel like the buffer was bottoming out hard. So overall, even though it was a limited test, I think I am on the right track.
Once I can get my hands on more 147s I’ll give it a better test with both the 308 spring and the Sprinco red.
