[QUOTE="Greyfox, post: 1644714, member: 10291"] I You are correct that powder selection and weighing accuracy can certainly come into play with SD/ES, but unlike a powders temperature stability which tends to be independent of the cartridge/rifle, SD/ES is influenced by a multitude of variables controlled by the individual as well as the barrel/chambering characteristics. Another shooter with a load similar to yours may very well achieve a better or equivalent SD/ES with a different powder with his barrel and methods. I have personally been able to achieve low SD’s(<5) with Varget, H4350, and R-16(amongst other powders)by optimizing my parameters. I would agree that some powders achieve SD more easily then others, but IMO it would be difficult to build a reference chart. Chemical properties like temperature stability and burn rate, on the other hand, are measurable determinants of the powder alone, enabling the use of fairly reliable reference charts. [/QUOTE]
