Yep, those sound familiar DM[8D] But they aren't what I want if we're talking 'Dream Rifles'. Besides liking the idea that I could make all my handloads from 30-06 casing (I always flip-flop between 6mm-08 or 6mm-06) most of the cartridges would more closely resemble an AI .243 or AI .280
I was searching around a few months ago and found that I had already been beaten to my idea.

...and I chose metric naming (yes I know the 30-06 half of the name isn't metric) because I really like the old mausers. In reality I'd be just as likely to by a 6.5swede or 7mm in a modern gun and handload it up to 'modern' levels.
