Two quick follow ups --

The cases that wouldn't chamber with normal pressure on the lever turned out to have rims that were 3 thousandths thicker (.063) versus the fattest rims that did chamber (.060). Most of the fired cases I measured were .055-.056 thick. I imagine a bolt gun's better leverage could force these, but I didn't want to take a chance my first time out with the rifle. (Looks like SAAMI specs call for a rim thickness of no more than .070, so mine may not be cut deep enough, or may have dirt or something impeding seating of the rim into its recess.)

Second, the issue with cartridges hanging up on their way into the chamber is definitely eliminated using pointed bullets like the Hornady LeverEvolution 325gr FTX bullets. Something like SDH-MT's custom spring and plunger would be a better option, but this at least makes one type of round trouble free for loading. I'm looking forward to seeing how they shoot.
