Here are some pictures of a 405 gr.copper clad aerotip PB I recovered from an elk,found lodged just under the hide on the far side.Shot was at about 25 yards it hit rib on both sides,shot from TC Omega with 95 gr. 2f 777,I shoot hornady 250gr sst's normally for whitetail with great results,but in Co. sabots are not legal to hunt with.As you can see the PB held together and had near 100% weight retention.
