My 6mm & 22LR barrel blanks should be headed from Lilja to CPA soon.
On the 6mm I had an epiphany the other day. Although I have the 6mm 30-30 Ackley form set, dies and 375 Winchester brass sitting here, Starlinebrass just released a run of 444 Marlin brass. I can use the #1 Form die from my old 30-06 to 22-250 Varminter form die set, then run it through a 358, 308 and 243 FL die with the expander rod removed and make rimmed 243 brass from the 444 Marlin and gain a couple hundred fps. It wouldn’t be a big deal to chamber the barrel using a 243 Winchester reamer and then cut the rim groove on a lathe.
I was waiting until I had successfully made up a hundred or so cases before letting CPA know that I changed my mind. They need to be trimmed to length and have the necks turned, but everything is looking good.
