I shot small bore CBA postal matches for a couple of years with a Pre-64 Model 70 and that bullet with 12 grains of 2400. It shot such small groups that by the third year, nobody signed up but me. FWIWBeagle
I have a yet to be shot 257 R, and the 257312 FP that came with it. Figured I'd never shoot cast in the rifle and prob part with the mold. From your post, sounds like that might not be a great idea. Any load dope on that mold/bullet for the 257 R? Thanx
