My brother has an 8mm Mauser and loads the 177 gr. Hornady for deer - he says they work well - they mushroom in a typical way. He doubts they're worth the extra cost, nothing special. He's not an in-depth handloader and doesn't experiment.

I read Xausa's message that he DID recommend the bullets for elk, moose etc. but not for deer. But I think frankly anything from an 8x64 is going to pretty much destroy a southern whitetail. It would be great in Saskatchewan!
