I purchased a NOE .225 45 grain wfn mold a whole back. From the get go, it's thrown nice bullets out of W.W's. The first time I tried to get gas checks on them, I about broke my fingers. The shanks seemed a little big. I switched from Gator checks to Hornady and still have the same problem. Finally, I measured the shank and it's .214. Both brands of checks measure .211. Is there something I'm missing here? I'm new to casting, so if it's painfully obvious, be kind. Any help from you boys would be appreciated.
