Not yet, partly because I'd yet to find a load with one of their powders that was #1 in any of my rifles. But the folks that are handling VV powders in the U.S. now noticed the article, and suggested I try some of the recent versions of some of their rifle powders, which are supposedly very temp-resistant. Evidently VV's been working on that, and a sample of five powders, all the latest temp-resistant versions, showed up last week.
This is good news. I've used some VV powders in the past, but limited to only a couple of calibers/guns, and each time I've been happy with the results. I'm looking forward to your update when it comes.
