I have a Winchester M70 which I am going to rebarrel to .257 caliber. This has an intermediate length action which will allow an OAL of around 3 inches. I am thinking seriously of the .257 Roberts RCBS IMP. with its 28 degree shoulder, because I'm thinking that it may feed better than the Ackley Improved version.
I also have 1000 .308 cases and very much like the .257 DGR, but I think it is a bit of a waste of space in an intermediate length action, however I can neck the .308 cases down to .270 and then .257. Any comments?
