Shot some of the 600`s from my White Bison today with 80 gr Graf 3f, shot 10 shots at 52-54 yds, didn't get any groups as 1st 5 shots were so far left couldn't see them hitting edge of paper..
Finally walked down and seen where they were hitting, loaded and shot 5 more on shot 2 noticed my scope ring had vibrated loose in the weaver mount and was moving around.. on 3rd shot hit about 5 inches high and 4 in left of X, adjusted scope and shot last 2 and they never even hit paper so the 600`s may of just destroyed a Burris scope
With the 80`s grains it kicks about like a 20 ga shotgun but is more of a hard push then a slap so not too bad, don't want to find out what 120 gr. is like.
