A musket is a status symbol among the tribes, even though it is not as practical or reliable as a hunting bow. A musket does, however, have a greater killing power and range than a bow. Warrior tactics in battle closely resemble those of European skirmishers, moving as small groups and firing as individuals. Massed volleys are almost unknown.
Historically, the tribes used whatever smoothbore muskets they could obtain by trade, theft or conquest. It was highly unlikely that any two guns would bear more than a passing similarity, unless the tribe had managed to ambush and defeat a European military unit.
