I've shot the 80 gr. A-max quite a bit and it performs same as the 75. It is not like the jacket is thicker or anything.

It's only saving grace is it's extra 5 grains which slow it down a bit and perhaps take it back from edge of blowing up in flight in the bigger offering- particularly as they get up in round count.

That is about the only reason I can see for it's being made. The 80 only has a moderate BC jump hardly making up for it's extra weight. Fine bullet non the less.
