I had a bit of a problem twice from the SST's blowing up on close range shoulder shots on hogs. BUT, in all fairness, I load pretty dang hot and with a 28" barrel I get some pretty sporty MV out of my MLer. It takes a dang tough bullet to stand up to my speeds at under 20 yards on shoulder bone. I had the same problem with them from my 7mm-08 on whitetail as well. It's why I switched to Interbonds and Interlocks. The SST's always flew exceptionally well and I never had problems with accuracy from them but I tend to get close with all my rifles so I have to use a pretty tough bullet.
