Re: long range 7 mag
Ditto, I shoot 100 looking for 1/2-3/4 group, then to 200, looking for 1 1/2-2'', then I go to 400, looking for 2-3''. Most factor rifles of mine have done this. Then I work them out farther until 1000. At the further ranges I only shoot in no wind for developement until proven.
