[QUOTE="Snowbird, post: 1648364, member: 87588"] thanks for the replies. ballistics guy, that's quite a comprehensive post. thanks for taking the time. my goal has been to get consistent 1st round hits on steel at distance with wind and other variables accounted for. what i'm trying to avoid is cumulative errors like left to right wind with spin drift (barrel threaded right) or shooting west at long distance when it is cold out/ east when warm. i was just unsure at what azimuth people commonly disregarded the coriolis effect. i have a factory 6.5cm that shoots under 3" groups consistently at 900 yards but haven't been able to shoot East or West with it. my other semi custom rifles don't do that. they'll hold MOA out that far though. so for my rifle it seems anything under 600 yards on an moa plate i will not correct for. after that i will likely correct with .1mil if shooting due E or W respectively if i have an aggravating factor. i'm really trying to get better at recording and interpreting my data. DOPE books aren't my thing but i see the value after trying to chase down previously gathered info. wish i would have started one sooner. [/QUOTE]
