What does whoever is in the white house have to do with gun powder burning rates?
R15.5 looks like 15 and 16 had babies. Sounds perfect for the 375 H&H where 15 excels but is not very temperature stable. I have been getting good results with R-16 and use that anywhere R17 worked before. If I see this with out hazmat shipping fees I will definitely try some.
My thoughts exactly.
