Well NoFun, if you're still in here, I recommend the 6 BR. For what your stated goals are it is better than the .22-250 standard or AI. How many 300-, 400- or 600-yard matches have been won by a .22-anything?
The 6 BR is one of the most efficient cartridges ever made. It will shoot a broad variety of bullets and powders as well or better than any other cartridge. Recoil, muzzle blast and torque are very minimal. I have two 6 BR barrels with over 2,800 rounds each through them and they will still shoot 1/2 MOA even though Lord knows where the lands are anymore.
If you choose a 6 BR with 1:10 twist it will accurately handle from 55- to 90-gr. bullets and you will have a real shooting machine. Enjoy!
P.S. It will change your handle from "nofun" to "wayfun"!
