    I actually used to know the answer to that, Standard charge for a 12lb solid shot was 2 1/2 pounds of Black powder. I fired one for 8 years as a park ranger. If the enemy was close you could fire double canister. Canister being 27 iron balls about 2 inch diameter. so double would be 54 balls flying at you. Fun huh? I'll look and try to find the MV.

    Where would you find the projectile?

    Think they make Pyrodex pellets for that thing? :D

    Happy to bring my own powder. Gotta buy a coffee can and fill it with scrap. Chattanooga is on my list of "to see" parks. Perhaps in Dec. of this year. How's the weather?

    Imagine the fun of charging up that hill with a couple of 12 pounders double charged with canister looking down at you.

    That hill is so steep that just charging up with full battle load would kill x% of the troops through heart failure or overheating.

    Frickin' cold. Or maybe a balmy 60-something. Possibly 40-ish and wet.

    Gotta love this corner of the country during monsoon seas... er, "Winter." :D

    Well I just cranked through Tennessee northbound on my way back from Florida to Illinois, and it was cold and wet at the end of October. 50's and rain, rain, rain so I can't imagine what it is like in December. Of course, in December, in Illinois, your powder won't just be wet, it will be frozen.

    Range Tables

    There are Charts known as Tables of Fire they will give all the necessary data on elevation, range, and time of flight for various projectiles. id send a picture but i dont have one for a napoleon. only a 1841 6 pounder.

    also to the former post, canister contained .69 cal musket balls. the 2in balls were in stands of Grapeshot. but yes double canister is a scary thing. i know our unit fired into a stand of man shaped targets. we wiped a whole company out and then some.

    Ok, I just looked it up and the canister round for an Army 12 Pound gun was 27 iron balls 1.48 inches diameter. So we were both off. Oh well, Still can bring down a world of hurt.

    BTW if you look on www.aaamunitions.com, you can buy solid shot, cannister, exploding rounds etc for the Napoleon. $120 +$15 S&H a piece.

    ooops

    well i stand corrected on the canister statement
    but i do know its .69 cal musket balls in the old '41 six pounder.

    just a small tidbit, the older 1841 6 pound field gun remained in service with the confederate army till antietam, when Jackson's forces captured harper's ferry securing machinery to make new guns. the veteran 6 pounders, were relegated to home guard service, many seeing service aganst the brilliant barbarian Sherman.

    i know this because the artillery unit i reenact with helped to convince sherman it was a better idea to go burn columbia instead trying to enter Charleston.
