Deer 243, don't fall into the trap that because your particular rifle follows a certain pattern that someone else's rifle will do the same.
The Super performance SST load appears to be unbeatable for velocity. The disadvantage with this factory load is that the bullets are seated up to the cannelure and this a long way from the lands; at least in most rifles. This normally doesn't produce the best accuracy. It may not and probably doesn't make the slightest bit of difference in the field though.
Higher velocity will also have some negatives, such as increased throat erosion, increased recoil etc. Personally, I haven't used a factory load in any of my rifles (rimfire excepted) for over forty years. I don't trust factory loaded ammo while I trust my own loads implicitly.
