Has anyone ever done any? I just got back from spending some time with the folks, and my dad had a PILE of scrap .308 and -06 family brass with cracked necks, etc. that will be *perfect* for conversion to 45 Win Mag. There won't be any worry of confusing the stamps since these are about 1.5" overall. In fact, I think some of them are .308 x 1.5 caliber!
There is one additional step that is called for when converting brass to 45WM, and that is to case ream (or neck ream) the brass to enlarge the inside of the case to spec.
I am unwilling to spend the cash (over $150) for an RCBS case reamer set at this point. I have some 45 WM brass to use as a model (thanks VZ!) and I was going to make a casting of the brass and use those measurements as a start to make a reamer. There is a taper to the I.D. that I can see, so an off-the-shelf reamer won't work.
From what I have read, the case reaming process uses a FL sizing die, that you replace the expander bell with a guide collar, and at that point you run the reamer into the chamber to ream the I.D. to spec. Sounds easy. Anyone know differently?
I am going to anneal the .06 family brass and resize.
The challenge I face at this time is whether or not "anything" close in size to -06 family brass will work. There was a pile of .244 brass (aka 6mm Rem) that has the same base diameter, but with slightly more taper than a .30-06 round.
Just wondering if anyone has had experience with that brass. From the latest Hornady manual, Remington "replaced" the .244 with 6mm to be more versatile, but they are basically the same thing. I think annealing will get them soft enough to resize. If not, well, I'll know really fast when they all split during the FL sizing process!
