As most of you already know, the Power Belt is a conical bullet with a plastic skirt instead of a sabot, whereas the Shockwave is a standard copper plated, polymer tipped sabot round.
At 100 yards, from a clean bore (after EVERY shot!) the shockwave beat the pulp out the power belt. I kept clean groups of 1.5" with the shockwave and i was approaching 3" plus with powerbelts.
also, the shockwave with the "super glide" sabot, shot consistantly 4": higher at 100 than the power belts.
I tested 14 rounds of each bullet, it would have been 15, but i was getting tired of cleaning. out of a T/C Encore, the power belts clearly lost out. they're still super convenient though.
i will be using the T/C bullets for sure, but more testing is needed to determine where exactly my sights ended up.
i wonder what some of your reactions to this might be? just curious.
