Home Forums Reloading Varmint Rifles Most explosive 50 grain varmint bullet in the 223?

I guess I should have asked the question differently - what 40 to 50 grain bullet (prefer 50 because of wind conditions) will really get a prairie dog to pop?

I'll ask that way because, again, the little ground squirrels aren't a problem, it's the big ones.

I'll take a look at the Calhoun 42 grain too; they sound good, thanks!
