Currently working on the Modelo Polylactico and was wondering if anyone else had a good solution for sanding the longer Intermediate shells. I had no issues using a 6mm drill bit + painters tape shim as a mandrel for the Beginner 209 shells, but the Intermediates don’t have enough surface area or depth due to their smaller holes to stay on the other smaller drill bits I’ve tried. I suppose I could force/tap an M2 or M3 screw into the top powder hole but would widening the hole cause issues if its sealed well?
I also noticed that the shell models had inconsistent rim thicknesses in Orca.
- Headspace gauge/jig rim: 1.8mm thick
- Intermediate .355 rim: 1.6mm thick
- Beginner 209 slug and shotshell rims: 1.2mm thick
Obviously there would be an issue if the 1.2mm rims were used to headspace, preventing the thicker shells from loading, but wouldn’t too much headspace also cause trouble like light strikes and case bulge/FTEs?
38 special is going well. The armorer is testing it and hasn’t really had any problems. 327 magnum has proven to be a handful. I don’t regret choosing the 327 fed chamber, but likely we will recommend people go with the 32 h&r magnum chamber in stead. 32 h&r still used magnum powders, so you can really utilize the rifle length barrels. It is a very capable round, and the slight shorter chamber will play nicer with 32 long, 32 short, and 32 auto. I really like shooting the 32 longs out of mine more than anything. No problems other than the hotter 327 loads hurting the brass. The gun holds fine but the brass is wrecked with the hotter 327 loads.
