The most impressive have been the Swifts. I have yet to recover a Scirocco; they expand and go through everything deer-sized I've shot with them. The A-Frames are simply unreal. I have shot the following unfortunate creatures with them: Alaska moose, .338, 275 grain; common eland, .375, 300 grain, Cape buffalo, .416, 400-grain, and lesser beasts with smaller bullets. Of the A-Frames I've been able to recover, weight retention has always been over 90 percent, and the mushrooming has always been perfect.
