I'm wanting to build a medium 7mm. I have thousands of 7mm bullets and need a good cartridge to use them in. I havent found much on the interweb in this class of cartridge. I have a 7x57 and 7mm-08 isnt out of the question but I'm thinking along the lines of the 6/6.5 Lapua size or GT size case. It needs to be something I can find/modify dies for and fire form from something that's somewhat available. I have a machine shop so modifications are at my fingertips. I'd like it to handle a decent array of weights, say, 120-140 grain. FIRE AWAY FOLKS!
