Had the opportunity to fire my gun today. I had 410 slugs and 45 colt, no bird shot. I fired six 45 Colt; no issues. Loaded one 410, fired it no issues. When I attempted to load more 410, I found the cylinders had developed carbon rings from the 45 Colt rounds preventing them (410) from chambering. My 454 will do this if you shoot 45 Colt in the 454 cylinder, but only after a bunch of rounds. What puzzled me is why did the single/first 410 chamber? The gun was/is used and not cleaned.
I’ll clean the gun and try it again.
