LOL... Too funny.

OK - so if someone did make a bullet with a high BC in those calibers, the projectile would weight so much, you wouldn't want to shoot it. the velocity would be low.. And the drop would be nasty.

Consider to get decent BC's in a 30 cal, you need to. Use a ~209 grain bullet, by the time your at 338 it's at least 225 grains..
