I'm still having an occasional failure to feed with the reformed brass. I caliper measured about ten loaded reformed brass rounds last night and compared to factory and the SAMMI specs sheet it seems good. I'll have to hand cycle a few loaded through to see if I have one bad piece of reformed brass or if it is something else. All the reloaded factory 300BLK brass works fine with the same bullet/load so I am thinking I need to check my shoulder forming. I really need to get a case gauge but I've had a hard time sourcing one so far. Calipers get old. lol
