I am itching to try out some new factory ammunition that is capable of long range shooting as well as big game hunting such as elk. In other words I do not want to shoot one type of ammo then have to re-zero my rifle everytime it gets near fall for a hunting load. Can anyone tell me what the difference is really between the SST super performance and the SST custom? They both seem to run the same numbers, the only difference I see is price and the box. Has anyone had any good or bad luck with these rounds? I already tried the SST super performance, the stuff in the red box and was minimally impressed with the grouping. Perhaps 3100 fps for a 180 gr bullet is more than my rifle likes.
