.204 doesn't offer anything ballistically that can't be had by existing cartridges.

Nice suggestion on the 22-250 AI however I'm not a handloader and I'm not interested in fire-forming brass and all that other nonsense.

All I'm hearing are horrorstories about the .223 WSSM. Also, the fact that they requirechrome-lined barrels doesn't speak well ofbarrel lifeand/or accuracy.

If I could find a reliable supply of 22-250 AI factory loads I'd be all for it. I knownext to nothing about the cartridge.

Thanks for the suggestions thus far.
