From what I've seen them do to deer at 200yrds, I'd say they work fine on deer sized game. There was no bullet recovered from the deer. (Small southern white tails with a 300WM @ 200yrds) I don't think I want to use them on elk though. My mom uses them on elk out of her 7mm and swears by them. The only problem she's ever run into with them was weak loaded one that didn't sound quite right when she shot. They found the bullet lodged in the elks hair when they skinned it. She said it mushroomed like it should, but never penetrated the hide.

I've got about 100 rounds of once fired brass that I'm going to reload as soon as I get the rest of the equipment. I'm thinking of using either TBBCs or Partitions, whichever shoots best out of my gun.
