One year i killed 5 deer with 300g sst. What i saw inside didn't particularly please me. One of them deer took me on quite a trip, after it was lung shot. The snow ran out too. It took some doing, but it ended in the freezer. That was the last time i used that bullet.
To me the Deep Curl seems to be a better bullet than an XTP. Behind my target i find bullets i shot, here and there, especially after a rain storm. The Deep Curl are always in better condition than XTP. Deep Curl hold together; XTP are mostly in pieces. However, i have no problem using XTP for hunting, because i don't hunt rocks and dirts.
