Let me work a little on the .30-30's

I thought I did some before but I can't find any notes. I first trimmed the rims, used a tubing cutter to cut at shoulder, my lathe to trim cases to 1.250".

They really need to be expanded to get the case taper out then sized back down to proper specs. A .401 sizer expander ball would be handy. Easier said than done. May make a tool perhaps. It all depends if the cases need inside reaming. That's a real buzz kill and would make me just stick with .41 Rem. formed cases.

It's a little whacky but it MAY be possible to use 10mm Auto Magnum Starline brass and headspace off the case mouth in the revolver cylinder. Long shot, might be worth checking. The solid case heads would be contained fully in the cylinder. It's a chambering and dimensional thing. I'll look at it.

Internal capacities do not really matter as you are tailoring the loads to YOUR cases in YOUR gun. Can't be a wrong capacity. You start low and work up, always.
