[QUOTE="bgordon, post: 23348, member: 519"] Just wondering how everybody utilizes group size and shape as part of determining the "best" load recipe specifically for ranges of 500 yards and beyond? For me, at ranges of 300 yards and closer it is a no brainer. I try to do load development on relatively still evenings so that any wind induced stringing is minimized. At 500 yards and beyond, it seems like no matter what I do there is some horizontal stringing. My best method is to do 5 shots as quickly as can be done accurately. If I try to read the conditions on each shot and space the shots far enough apart to keep the barrel cool, there is a definite amount of horizontal grouping to the shots. The horizontal spread happens most of the time, unless I just happen to get good (or lucky) at reading the conditions. For this reason I normally use the accumulated vertical dispersion of 2 or 3 five shot groups to determine load potential at 500 yards and beyond. [/QUOTE]
