I shot two deer with that bullet in my 25-45 Sharps last year. They were clocking in @ 2822 fps out of my SRC 18" barrel. They were accurate but I wasn't really impressed with the bullet performance. At 100 yds, I shot a big 6 pt cull buck and he ran off after the shot. Complete pass through, blood on the tree stump behind him. He made it to my CRP field and I lost his trail in the wet broomweeds. There was very little blood to follow and my neighbor found him the next day. The coyotes had already found him and he was a total loss. I shot a good sized doe @ the same place and she ran off as well. Again, very little blood trail but I was able to find her about 100 yds from where I shot her. Both shots were behind the shoulder and were double lung hits. I will not shoot deer with that bullet again, I'll save it for hogs and coyotes or for target shooting. I switched to Speer 87 gr SP bullets for deer. It is the same bullet SRC uses for their factory loads. BTW, when the Sierra was the only 87 gr bullet I could find, I emailed Sierra and their tech guy told me that although the bullet was a "varmint" bullet, they would be good for deer at my velocities. Not so much in my experience. I shoot a lot of Sierra bullets but won't be buying any more of these.
