Having a problem where the bolt does not strip rounds 2 or 3 from the magazine. It overrides the cartridge rim and jams between the bullet and the feedramp. I can hand cycle ammo though the gun perfectly, but it always jams while firing.
I've already done the following:
- disassembled, cleaned, and reassembled the barrel jacket
- replaced ejector to fix ejection problem
- straightened mangled mag lips and re-crimped like an unmolested mag to fix nosediving cartridges
- checked mag body for dents, magazine spring orientation, follower moves freely
Ammo is not the problem; my friend has the same gun and my reloads run 100% in his gun. The only significant difference I can see is that his gun has a wider gap between the magazine spring clips (0.8" vs. 0.6").
