NZP I have only had one chance to shoot it at a target at 644 yds, using 168 bergers. There was a strong down valley wind, which may have had a right to left switch. First shot on the target was about 10" left but perfect for height.(I drove up to the target to check it was hitting and then drove back, made no changes) Next two shots were within 1.75" of each other, about 3" low and 3" left.
Not a 0.5MOA group but I feel the wind had a part to play.
The 162 a-max shot slightly better then the accubond, but I am now using 168 bergers as the 162 a-max were impossible to get for awhile there, I saw some idiot pay $180 for a box of 100 on Trade me a while back.
The bergers shot the same as the a-max, I have taken red hinds at 594 and 442 yds with them.
Looking at how soft the berger and a-max are I don't think I would ever use either on close game.
The berger and accubond shoot to the same POI so that is handy.
Stu.
