[QUOTE="Shootin4fun, post: 1336551, member: 28741"] The OP asked about a good distance for load development and described a process of shooting only 10 rounds at different load configs. People were saying anything other than 600 - 1K is a waste of time, meaningless. My point was originally about sample size and distance. Any error induced by the shooter can affect vertical or horizontal. Wind can too, depending on direction. Sample size must be increased; single shots are highly ambiguous. I haven't missed anything about vertical dispersion...I look for it in my 4 shot load tests, as well as the relative distance and position from POA as Newberry suggests. Last weekend while testing 168 7mm Berger Classic Hunters with RE 22, 2 of 3 loads showed about than .1" vertical dispersion @ 100. Horizontal was .4 & .5 which I'm thinking was the strong coffee that morning and trigger technique variance as there was little / no wind. But that may not be the case, because another standard load I have with Classic Hunters & H1000 shot 3 of 4 in one slightly enlarged hole with the 4th .3" higher twice, an hour apart, same relative POI. I will rinse and repeat this weekend @ 200 & 300 to verify these assumptions/conclusions. Sample size. In general, I have not seen things change due to a load configuration between 400 & 1000 yards. If it's shooting .5 MOA at 400, it's capable of that at 1000, so I don't see the value of doing load development at 1000 where it is more likely wind, sight picture and other human variations that cause group size changes. This is assuming high quality bullets of course. If someone can explain how that's not the case, I'm all ears. [/QUOTE]
