My dad was an SST fan for a while but he started having blow up problems on close range impact shots from his 7mm.08. I would suggest you take a look at the Hornady loaded ammo with the interlock bullet. Much stouter bullet to hold up on that close in shot if you get lucky enough to get on a Bull under 70 yards. 7mag speeds are around 2950+ with store bought ammo. I have mine at just at 3050 and can get a good deal more but my rifle loves that load. Those speeds require a fairly stout bullet for close range impacts and the SST's are far from a stout bullet.
