I have one of Mihec's .452-200 molds and have cast a few hundred solids with it. Mihec's molds are works of art. I loaded some of them for my early 90's Colt Officers Model, using Colt mags I bought at the same time I bought the gun.
When I loaded the first few rounds and was checking the fit I loaded them long with about 1/16 of an inch of the drive band showing. When they are loaded from the mag they hit the bevel on the bottom of the barrel and put a flat spot on edge of the flat point of the boolit.
Then I read on this forum that for auto-loaders you should only have "a fingernail's width of the top band showing", so I have loaded some to those specs and they are still hitting and flatspotting. After shooting 6 rounds there was a lead smear on the barrel where the boolits where hitting it before feeding on into the barrel.
Can someone help me with this?
Thanks in advance.
