RE: 270 brass just a necked down 30-06?
Trade some of that 06 brass for some 270 brass. Somebody reading this thread has probably got some 270 to spare and is in need of 06. I tried doing that with a regular 270 sizing die, not really researching it first and pretty much ended up ruining my die when the case got stuck and I had to grind it with a dremel to get it off the sizing ball. Oh well lol, we all learn somehow.
