Re: Experience with Hornady SST on deer?
Shooting 120 grain in a 6.8 SPC at ~2750 fps. I've killed 2 deer with them, one at 30 yards, one at 275. Both had ~1.25" entrance and exit wounds through the ribs. Both deer dropped immediately and did not get back up.
The SST has worked well for me on whitetails. There were a few pieces of jacket recovered from both animals. It's not a bonded bullet, basically most of the nose is going to disappear forward of the interlock ring on the inside.
A fair comparison bullet would be the Sierra Pro Hunter, or the Nosler Partition.
I spoke with Hornady about pushing these to extreme speeds with a 300 RUM, they stated that I should stay below 3400 FPS with the SST.
