So I'm sitting around talking to the father in law after the kids got done hunting egg about reloading for the old shoulder cannon yesterday, when he he hands me an old RCBS JR2 press he found at the pawn shop along with a set of 45-70 dies and a #14 shell holder. The press has some rust but it moves freely and there's virtually no wobble, so score one for me. The only thing that concerns me is the end of the ram. It won't take a shell holder, but instead looks like it's machined for one shell size. 30-06/308/243 all snap right in. Does that mean you have to change the ram to change shell sizes? I've been hunting around the net and haven't found anything even remotely like this yet. I know this is a long outdated press, would RCBS be likely to have a different ram for it anymore?
