I have recently zeroed my A-bolt in at 100 yds adjusting the BOSS to get a fairly tight group. However when i moved out to 200yds, there is about 2" between each shot. Given that i could be shooting out to a much as 300yds, i would like to get the group as tight as possible. What sort of group size do you guys think would be reasonable at 300 yds? I assume the BOSS can be adjusted to tighten the group at this distance??
I intend using this rifle in my trip to Africa in the next few months and i am obviously keen to get a solid zero before i go out. My thinking for the 200yd zero is that the ( 180gr Barnes TSX ) bullet drop at 300yd with this zero is only 4" as opposed to 11" if i zero at 100yds!
Any thoughs would be great.
