Ok.. The 444 marlin collapses when I attempt to neck down to 35 caliber in my 350 Rem Mag die. RCBS doesn't make case form dies. Any suggestions welcome...trying to be as cheap as possible.

I do have some 308 Marlin cases with a false 8mm shoulder ready to fireform with 150 Hornady RN's. Should create a nice short necked 307 that will work with the longer 160 FTX made for the 308 Marlin Express. b.c. of almost .400 at 2500fps+ ought to be quite the caribou load.

If I can figure out how to reform 444's for full length brass I'll be in business.
