I have used the 100 grain Prohunters in my 6mm, kills deer in their tracks. Same with the 85 grain flatbase Sierra Varminter.

Have used GameKings for deer in .22, .24, .25, .27 with same results, dead animals and none of the failures I read about. With these 4 calibers and probably 50-75 deer between a buddy of mine and I there is enough of a sample size to say they work pretty damn good.

The last time that bear ate a lawyer he had the runs for 33 days!
