I should’ve mentioned as well that I am doing my best to take a somewhat safe educated guess at this. I watched the video in the above link to get a feel for what worked for Johnny. I combed the web and also found some QuickLoad data and used some common sense as to whatever “falls between RL15 and RL16” on the burn rate chart according Alliant means from their advertisement. Judging by Johnny’s results I think he put it best as it probably more like a RL 15.2. My theory is that it’s going to burn closer to Varget and Winchester 748 which is hardly the middle ground between RL15 and 16 and where Leverolution is found. This however is why I’m interested. For me Win 748 is thus far the most preferred powder for my Criterion barrel. The rumored outstanding temperature stability is maybe even a bigger reason to try it out. That’s one area the W748 is falling short. To be clear this is an 18” gas gun doing the work. I believe the high 27 and especially the 28.2 gr loads to be way over pressure but just want to confirm for myself since each rifle is slightly different.
