Roundball/Maxiball Ballistics

Below are Thompson/Center Arms' suggested loads from a paper publication of theirs, printed in October of 1980. All of these loads specify no. 11 caps or T/C flints. Round ball loads specify T/C patch material lubricated with T/C no. 13. Maxi-ball loads specify the use of Maxi-Lub as a lubricant. FPS = feet per second at muzzle. Ft-lbs = foot-pounds of energy at muzzle. Grains listed after projectile type represent bullet weight.
