If you have trouble with the 162g A max, play with the seating depth. I have one that loves a kiss, another that loves to jump 0.040. Lots of guys give up on the A max due to bullet being particular on how it likes the seating depth in that particular Gun.

A max's have less bearing surface than the 160g Sierra or the 160g Accubond and it does have an effect on pressure.

Moly and wax will do away with vertical at longer ranges, take that to the bank as the standard deviation will drop to single digits.
