Re: 162 A-Max (7mm) & 140 A-Max (.264) for deer and or elk?
Just to be sure of adequate penetration, use the SST in the same bullet weights.
I doubt you will have any problems at those muzzle vel, BUT there are times when you need to take a "poor" angle shot.
I hunt with the SST and have never had a problem. They are wonderfully accurate and sometimes even have a higher BC then the Amax or matchking.
