The light bullets are going to blow around so much that they really wouldn't be much good beyond about 200 yards, anyway (poor s.d.). Out to 200, those little guys can spell poison, round nose or no. A friend had a .257 that would ONLY shoot R.N. 120 .257. Sure the B.C. stunk, but inside of 200, who cared?
I guess the question is what you really wanna do with it. I personally find 3100 fps to be plenty good for "blowing up small mammals." What, the mist gets pinker
when you get MV above 3300?
