Luke,
I think you'd be just fine, the cutting diameter is less concerning than the angle of the blades to me because they're not that wide of a cut, but it IS and acute angle that those BH's have to them. I have plenty of energy for just about anything on the market, but I might hesitate to us the Grizz-Tricks. The ST Magnums however are an excellent BH, and have a more sloping angle that doesn't seem to affect penetration. Granted, ST are SHARP, but that angle on the Grizz-Tricks "scares" me away from them.
