The Black Hills Match 165 gr. Soft Points worked well for me this last season. This 'trophy' buck went about 10 yards before leaning against some brush and dying. It was sorta funny because although it was very dead, it looked alive (it was still on all fours with its eyes open). My wife walked around a tree and saw the deer from about 5 yards still on all four legs and let out a good scream.
The good part is that the ammo shoots excellent and is relatively cheap (about $15 per box when on sale).
