It's as comprehensive an all-inclusive list as I've seen. Powders come & go, and no two sources seem to agree on exactly where a given powder fits, but this one roughly agrees with my other lists I've accumulated. All but one of the powders I've got (39, from many makers) are listed, in roughly the agreed-on place. Thanks, this is useful. Phil E
Phil, Some of those powders aren't available (No. 206, W-780BR). If anyone has some they want sell, I will talk. I have a 25-06 that will shoot the eyes out of mosquitoes when loaded with that. I heard that it went out when Winchesters production facility in Florida burned in the erly 1970s. I tried all over the countyry and couldn't find anymore. The 25-06 and I have both been grieveing since then.
