[QUOTE="morcey2, post: 1031354, member: 71004"] That's almost correct, but not quite true. The 6mm rem has a steeper shoulder angle (26* v. 20*) and a shorter "body". 7x57 and 257 Bob are both 1.7277" to the shoulder while the 6mm is 1.7249". I'm building a 6mm also and brass availability was my biggest concern. But it was more of a concern to have 257 Rob brass for my already-built-and-shooting 257. I picked up 200 once-fired 6mm Rem cases and culled them down to 100 good ones. I used some of the less-than-savory cases to experiment with reforming them to 257. It didn't work very well due to several factors. Thankfully, the Nosler brass became available at about that time so I stocked up. I don't think there is much of an issue with forming the 257 to 6mm. The shoulder will be worked and pushed back more than it would with forming 257 from 7x57, but it should work. Matt [/QUOTE]
