I shot a goat out on Kodik Island w/ a SST from my 300 wsm. I will never do that again as it blew one heck of a hole on the far side. Since then, I pretty much exclusively use TTSX's in all my rifles.
Greenbrier nailed it, the SST rip things up. we staple our targets up on plywood at our camp, and the SST bullets, it doesnt matter which caliber(we have the from 25cal to 30cal)just splinter the plywood compared to some other bullets that we load.
I know I've put this up before but this is a .270 150 sst fired into ballistic gel with an embeded deer pelvis. 2900fps impact, a little slower than the 130s but with a .529 BC these things hum. I'm crushed they are now "seasonal" run whatever that is. Have to buy a pile when they open up again.
