Im a bit stuck. With the component shortage now spreading world wide i have found i cant get any FFF from my usual sources and can only get FF and 4F. I shoot a 1858 Remington 44 Uberti replica and have only used FFF . Can I use any of the 2f or 4F instead, and if so what sort of loads work. I load 23 grains of 3F with a semolina wad and a 457 round ball topped with a lube of beeswax and petroleum jelly. Very accurate and fun to shoot. I live in NZ and am at the end of the supply chain so don't expect to get resupplied soon. On the other hand I can still get primers and powder altho prices have risen.
