SonnDog,

I've owned several .204's,all with the standard 1-12 twist, and have had great results from all with plastic-tipped bullets from 24 to 40 grains, at elevations as low as under 2200 feet in eastern Montana. But these days I mainly stick to 40-grainers, since they drift noticeably less in the wind than anything lighter.
