I have the opportunity to pick up a Remington 700 VRL in 6mm Rem at a good price. I am currently shooting Tactical matches to 1000 with a Rem 700 in 308 and would like to get something in 6mm. If I get this rifle will I be happy? I'm concerned with getting quality brass. I know I can form from 257 Roberts or 7 x 57. I've never done this and don't want to get the rifle if it will end up being a lot of work and trouble. Too much brass lost at matches. Would it be practical to rechamber?
