[QUOTE="maximini14, post: 907118, member: 76297"] I am interested in improving on the 7mm rem mag. My thought was to run a reamer thru my A-Bolt to yield greater case capacity by carrying belt diameter thru body. I was thinking why can't one have a chamber which is .532 from rim with minimum taper to shoulder. Push the shoulder forward using a 35 deg shoulder angle while maintaining the standard rim to neck length of 2.229 and maintain 2.500 case length. The 7mm RUMs and STWs would require a larger bolt face or magnum action to accomadate the 3.6 COL of these cartridges and a longer magazine box- I think! I have contacted RCBS and they do not have a die or reamer like I desire and there does not seem to be an existing cartridge that brass can be formed from! Any ideas? [/QUOTE]
