Re: B.C./Drop Report--MUST READ&COMMENT
RockZ, How big was the group that determined this 2" @ 100yds? And the rest of the drops?
A lot of room for error and variation in this kind of scenario. If you want to make any sort of reasonable conclusions you need more precise data and more of it at longer ranges. This simply does not tell you much. I have shot numerous sets of groups from 100 to 600 yds where not every set "fits" into the a particular BC or trajectory. Go out and actually try it some time. Shoot some 3 or even 5 shot groups at 100, 200, 300, 400, 500 yds and you will be lucky if any 3 sets of groups perfectly match a BC trajectory. Then go out and try it again the next day. I can just about guarantee you that your data for the two different days will not match with 1/2" consistantly. Especially with a sporter rifle.
