[QUOTE="Shootin4fun, post: 935528, member: 28741"] I like most have typically tried incremental charge tests and just looked for the best grouping without placing much importance on POI relative to other charge levels; in other words judging each charge on its own group size only. I shoot mostly between 100- 300 yards in doing my tests and just casual shooting practice. But I can go to 400 without too much trouble and 600 if I drive a while. I have inadvertently stumbled across what Dan Newbury says about the POI of a string of charge weights. Also, I have seen where a tight ES & SD on the chrono doesn't necessarily correlate to a tighter group, though of course a very wide ES & SD lead to large groups at longer distances. I have also noticed the correlation of a "favorite" velocity or velocities of a gun. Gee, wouldn't it be nice to be able to load up to a certain velocity regardless of bullet type or weight, and always have the same level of accuracy??! I am currently setting up to do a strict OCW sequence at 100 yards. I'm using a powder/bullet combo I've already experimented with and know can hold low velocity variations for starters. I will chrono as I go along. It seems to me that if the OCW I find also shows a low ES and SD on the chrono, it should be good at much longer distances and result in what Jason Baney calls the "accuracy window"....We'll see. As in life...+1 on that. [/QUOTE]
