The 38 cal XTP from Hornady handle some high impact speeds very well, from some tests my brother and I have run, using his 357 Marlin CB. He got some 180's up to about 1650 (not std pressure) and shot them at alternating milk jugs and half-inch OSB pieces between every 2 jugs. The first test was plain milk jugs from 20 yds. It went through all 11 jugs. The next time we were out, we used the OSB. The 180 XTP went through 5 pieces of OSB and was in jug #10, after rebounding off the back and puncturing #11. It was perfectly mushroomed, and weighed 134 grains.
I still couldn't talk him into going after elk with it though. They shot into 1.5" at 100. I don't get that decision. He has a couple boxes of 180gr Partition Golds that he got up to 1600. Another fine choice.
I'm sure a 158 XTP going 16-1800 would be slick for deer out to 150, or maybe a bit farther.
