I’m using mostly 3f in everything as well. The only exception is if I’m shootin heavy for caliber bullets. In that case 1.5f Swiss is generally the first choice. It’s clean burning and provides the best accuracy if not the most velocity.I have generally followed the "accepted knowledge" regarding grain size, except that I have almost always used 3F in revolver cartridges. (I've never come close to fitting 40 grains of it into anything other balloon head cases, and have found that with Big Lube bullets and Starline cases, 32 grains gives the 1/16" compression I'm looking for.)
The last few years, I have been gravitating more toward 3F everywhere, even .50+ caliber muzzleloaders. My newest .54 flintlock, for example, is faster, more accurate, and cleaner with 3F than 2F, and I can use a bit less of it too. It's coming up on time to make another 25 pound order, and I think I may switch from my traditional 50/50 order to something more like 90% 3F.
