RE: 777 FFG vs FFFG vs Pellets
How many shots per pound is a great question. I can get 80-90 in my flinter. I shoot 70 grains of 3F blackpowder. As was mentined earlier, it depends on how much you spill. I personally have spilled alot of it. The grass grows green around our bench.
Ilike 3F Blackpowder. Obviously loose. I believe the flakes are slightly smaller, and in my opinion gives a faster burn rate.
I think moisture has alot to do with accuracy, because I believe it directly effects the powder. I think it directlyeffects the burn rate. I normally hunt in cold inclement weather, so I normally sight my rifle in when the weather is a bit nasty. I have noticed on a bright, sunny, and dry day that my rifle will shoot different POI. Then I shoot on an overcast wet day, and I again have a different POI.
It may sound radical, but I believe weather plays a great trick on BP guns. Sorry, it may sound silly, but I believe it. Tom.
