Im stumped! I shoot a-lot at 200yds++. If Im dead on at 100 and a 1" or two off at 150 to one side or the other I blame it on me or the wind. If there's no wind, I'll try 200, if I get the same results then I adjust the scope for it, but usually it's only a click or two. But to be that far off and only adding another 20yds or so and being on at 100 puzzles me. I cant see the MLer being at fault, mabey human error.
Unless your shooting a Magnum Load? a-lot can go wrong with the wrong bullet powder combo at long ranges, but to be on still at 100 even with a Magnum Load and then to be that far off, it should'nt be.
