I'll be the first to come in on the anti powerbelt side. First off, these bullets load super easy and are the most accurate bullet I ever tried. With that said, I shot at 3 deer with them, first one was a tougher shot, never found any blood or sign of deer so I assumed i missed. Second one was a 50yd broadside shot. Same thing, never found blood and was shocked i missed. Next day I went walking in direction deer ran and by pure luck I found him about 75 yards away hit square in the vitals. I back tracked and no blood at all. Deer had no exit wound at all. 3rd deer was 35yds. Due to smoke i couldn't see deers reaction but as I said, these bullets are super accurate and I had a steady rest at a broadside deer at a short distance. No blood and i walked and walked. Never found that doe. I still didnt blame the bullets until i started reading others with same experience. I quit those bullets from that point on.
