Bananza - I know where-of you speak - Fun it is. I tried Trail Boss in my .45/60 35" bl. Sharps, using 15gr. with 385gr RN and 345gr.HP cast bullets. These were supersonic, though, maybe 1,200fps @ 2,000' ASL. A 12 gr. load would drop them to about 900fps. They're accurate for sure 1.3" at 100 meters for the 385gr. The .340's went 4". Shooting was with tang mounted peep and globed front cross hair insert. As to sound, still quite quiet and virtually no recoil - like shooting a .243.

This powder sure is fun to shoot. It's so light and fluffy - no mistake on level in the case - almost full yet has hardly any weight.
