Please help. My wife is doing a tactical shooting competition this weekend. I thought the shots were a max distance of 300 yards but I found out tonight they will be out to 425. Her rifle is a standard Sig AR with sixteen inch barrel topped with an Aimpoint T2 and Aimpoint 6x magnifier. I should have got her an NF 1x8 but it is too late now. I have searched but come up with conflicting info. Can someone please help me find a ballistic chart for a 36 yard zero for m193? I tried to work one up on several sites but the rise does not marry up . All other sites only give the numbers out to 300 yards. Please help.
