3F seems to be the all round powder. I originally purchased it for my 1851 Colt revolver. I still used it into my Flintlock Rifles but have since graduated to 2 mainly 50 caliber and above. I I have 1F and 1.5 . I reloaded 45 Colt for my Ubertie 1873 lever rifle with both 3F and grits as a filler and then 2F with a fiber wad or two. I read some where that 2 is what they used back in the day in cartridges. Fun stuff. I was wondering what people thought of using a little filler in a flintlock like a Brown Bess though I think probably not a good idea because of the difference in ignition primers vs touch holes. Would mixing say 20 grains of grits with 60 grains of 3F work. Does anyone blend there bp for low power charges? I mostly plink alot and with the brown Bess go through 1F and 1.5 like crazy in paper cartridges. I used to use 120 grains I sometimes prime from cartridges. I have 5 bottles of 4 F which is useless sorry I bought so much of it. You can get about 70 paper cartridges at 70 grains but the cartridges are chinsy in size id like to mix it with 30 or 40 in those. Again mixed not bp followed by grits like in a cap and ball revolver.
