I don' t think that' s too unreasonable. I like to shoot 1" groups or less at 100 yards which translates to 2" @ 200, 3" @ 300 and so on. Don' t expect to get tight groups like that on the first try though, it might take some experimenting with different factory loads or hand loads. Also don' t expect your favorite hunting bullet to shoot the best out of your rifle. My 270 will shoot 130 core lokts into .75" or less all day but I will not use them to hunt elk with. I can usually get right about 1m.o.a. with most bullets but some just won' t shoot worth a flip. Just keep trying till you get that right load wether it be factory or your own.
