I've used 3 50gr. pyrodex pellets and the powerbelt 295gr. hollow point bullet for 3 seasons. The 1st was a 10 point buck. He was all ruted up and charged in to my grunting through thick brush and busted out the brush at 12 ft. Scared the crap outta me. Shot him between the front legs and he dropped in his tracks.
The 2nd was another buck at 10 yards, perfect broadside, dropped in his tracks. The 3rd season didn't get one.
This really isn't enough time to judge this load. Even with great results, I've dropped down to 2 pellets and the same bullet after reading some of the comments on here. Don't know if it's alot of hating on this bullet and load of 3 pellets, or they're really true. I take everything with a grain of salt, just don't want to risk loosing a deer to a hot load.
But yeah just learn and practice your shooting at that range factoring in bullet drop and all that and ya get it in the boiler room and you'll be fine.
Good luck.
