Got this small buck with my Knight Wolverine this evening. Used 70 grains of Black MZ and a 295 grain Powerbelt Aerotip. For the people that says powerbelts don't give passthroughs here you go. Entrance, exit and into tree. Deer made it a total of 5 yards from shot.
70gr of BlackMZ is about the same as 70gr of Pyrodex.....really slow load, so yes it should work. Sadly its cost way more than a cheap conical that would do the same thing.
I tried conicals last year and get way better accuracy with the power belts. I also have a bunch of the shockwave bullets they shoot good also. May try one of those next.
