Those cups, just like most sabots, usually fall off 10 to 20yds from the firing point.

I've never found any melted cups - just ones grooved by the rifling........and occassionally grooved quite a bit. The problem I had when shooting the heavy powerbelts with 3fg 777, was I didn't find them at all - except one I found right BEHIND the target, 75 yds from the firing line. With the cups still attached, accuracy is deplorable.

All I can say is try it with your rifle & see what happens......... all of these front-stuffing beasties develop their own personalities - so it's worth a try to find that "perfect" load.
