So where do I start? I have been reloading, shooting, reloading, shooting the 500 for a few years now with no problems. Matter of fact, I've gotten great results with 4 different powders so far. YESTERDAY, drive to a friends house to test some work ups with Unique, once again- no problem (other than it sounded like a cap gun).
Brought a long a bag full of "tried, tested and trusted" loads I loaded with IMR-4227 (31.5 gr's) and 440 GC'd, Pc'd LCSWC. We decided to drive to a few fields in back to see if we roust up some pigs. Went to drop some rounds in cylinder-did not fit! Went a third of the way in! I immediately started troubleshooting my "mental memory" of what did I do wrong? I cast from favorite alloy (17 BHN), powder coated once with Eastwood, sized/GC'd, charged, seated, crimped. (Using Sage's Outdoors checks).
Possible causes:
Waited too long to size and check after casting?
First time using "CBC" .500 cases?
I tried some other rounds in cylinder I loaded exactly same way from a year or so and no problems chambering.
Question: Can I resize loaded rounds through sizing die with de-capping pin out and re-crimp? Or should I ditch the whole operation and pull em all?
