I searched everywhere and couldn't find any brass 44 Mag cases so I bought some Starline's in nickel.I wanted either Starline or Winchester and most were on back order. I tried running them through my size die and thought they'd never go in. I had to really put some pressure on the ram handle to get them all the way up and back. Plus, there were vertical scratches on the cases. I don't much care for nickel cases and wondered if this was typical of the breed. I have some cases in 45 ACP and honestly don't remember them being that difficult to size. I had to really put some pressure on the handle to get the case in and out of the 44 die(RCBS for 44 Special). Realizing the mag case is longer I backed out a little but that didn't help. I mean the whole work bench was shaking...what the hell's with this?
