My suggestion is to use the best Hunting bullet you can afford. Barnes Bullets, and particularly the TSX in 62gr or 70gr. For powder use BLC-2, or AA2230. I prefer ball powders, but there a quite a few good stick ones as well. I tend to get the best accuracy from not pushing the bullets to max velocity, usually about 300fps or so under max.
Also, shot placement is key for this caliber (as for any caliber, but this one especially).
