In my limited experience and humble opinion the hornady SST is an amazing killer if used in the ranges and velocity it was designed for. I've killed a number of animals culling and besides the speer 6.5mm 140 seconds from midway it's the second best killer for culling 10 yds out to 500 yds. Light skinny framed goats approx 70-100 lbs out to 1,000+ lbs wild cattle. I never had one not work and I've even killed my biggest bull elk with a 30-06 and 165 gr SST. I took a second shot on an already dead animal to secure him while we made a slippery climb to him 300 ft down a gulch. This is my go to bullet for anything in Hawaii but each bullet has its limits and purposes. I don't use them in ULTRA VELOCITY 3200 FPS+ but they hold up excellent in normal conditions. Test book mushrooms up against the far side hide!! AlohaThe one bullet I don't touch or own in my over 15k bullet collection is the Hornady SST. Had a few bad experiences with the 117 grain out of my 25-06 and sent them down the road. I didn't even save them for the coyotes for whatever reason. I have other Hornady bullets, eld-m, eld-x, interlock, interbond, etc but no SST's.
Edit.. I use them today exclusively in my 243 win 95 gr SST, 257 +P 117 gr, 6.8 SPC 120 gr, 7mm-08 140 SST, 308 125 gr SST, 30-06 165 gr SST and 300 RCM 180 SST. They all shoot 1/2" or less and of course better bullets exist. I've lost animals but it was from human error. Up to 500 yds HORNADY SST KILL.
