i was set on a standard 223 rem build on a 700 action but now im wondering if i should go up to a 6mm. Cant decide what i want. Im looking for a budget build just to shoot for fun and try to push wayyyy to far. Im not in competition nor will i ever be. Shooting in Wyoming. I just like to reload and figure up loads on my own. Now Im thinking I should look into a 6mm but I know I need/want for sure these things for my build... (1) brass availability (2) short COAL so i can seat 90g- 115g vlds and still fit a 308 mag. (3) A NON barrel burning round. I DO NOT want to have to fireform brass! Thanks in advance for your suggestions!
