Thanks Mec, That's the kind of info I like to see! If I load my Remington .44 with 35g of Goex fffg and a wonder wad over that and a .454. ball I still have room for a little less than 1/8" of grease over the ball. If I didn't use a wad and just used grease over the ball I'll bet I could get 40 g. of fffg in there but I don't believe I want to push it that much.
The gun seems to have plenty of power and still has good accuracy with 35g so that's what I use in the woods.
Now I have to order that book.
Thanks again, Mike
