PorkChop,
I've used both the 180s and 200 grainers. The 180s worked fine on the antelope and whitetails, one shot kills, either DRT or short track with pass throughs and good blood trails. Never recovered complete bullets, sometimes jacket material. Used the 200s on a cow elk, approx 300#, 30 yards, quartering shot, struck behind left shoulder, slug in right paunch, went about 20 yds. Only problem with the Kimber, throws the brass into the next county.The Glock 20s not so much.
