I have a home-made dipper (trimmed from a .357 Mag. case) that throws 26 grains of 3f (weighed). I've never tried it with filler, because I didn't know about fillers back then. I'll bet 26 grains of 3f topped off with a nice breakfast filler would prove to be a tasty load. :stir: I'll try it.
My Hawken .50 Cal. rifle likes 60 gr of 2f or 50 gr of 3f for paper or steel targets out to 50 yards, and does an adequate job on the steel 100-yard gong at the nearby shooting range. I also have a Jukar Spanish-style single-shot pistol in .45 Cal. that shoots fine with 2f or 3f. I use musket caps on both of them to get full ignition with the lighter loads of 2f goex that I tend to shoot. If I eliminate 2f powder, I may switch back to #11 caps. They're cheaper and more plentiful than musket caps anyway. I do like the musket caps, though, because I have arthritis, and the large 4-winged musket caps are easier for me to handle. I guess a good capper would be OK with #11's. (I use a self-modified Cash Capper for my revolver, and it works great!)
Do you think 3f powder would work better with #11 caps than musket caps?
