I am using 40 gn Berger's and H4895 (although, I might switch to some other powder, still looking there). I didn't want it to be too terribly fast out of the shoot (though I chronographed it at 3700 fps), since I am trying to keep the hides. But these bullets hold up fairly well downrange. I've been shooting over tops of some coyotes, thinking I would get more drop, but nailed one at 400+ the a couple of weeks ago that never moved. At close ranges inside 150 and over 100, the bullet does go on through, but doesn't blow off legs unless you hit solid bone. Have yet to try the 30 yard shot on a coyote with it yet.
