You didn't mention what you wanted to shoot them in. I have been using them since they came out in rifles at first and now in handguns. I have taken deer with them in my .243 Encore, 6.5JDJ, 7-30 Waters, 7-08 XP, 6.5x308 XP, 338JDJ#2, 30-06 Encore, 309JDJ and some others. Never had a failure. All one shot kills from 80yds to 405yds. I think from my experience they work even better at pistol velocities. They still do their job but are not as explosive as from my rifles I used to shoot.
I have taken deer, antelope, elk, hogs, coyotes, and prairie dogs with them. Get them and you will be happy.
