W.M.large

[Mike]

I need help i just picked up a W.M Large 54 cal slug/bench gun .What do i need to shoot it all i have is round balls?

First, check the rate of twist. Most likely that barrel is made for round ball shooting but Large did make many things. You might also check the depth of the grooves, if you can. The best way to do that is to un-breech the barrel so a slug can be driven all the way through but you might not want to do that. Another way to "test" it is to take it out and shoot it with a tightly patched round ball just to see how well it shoots. Large commonly made two sizes of .54s, one for a .526" ball (for hunters) and the other for use with a .535" or even .540" ball (for target shooters). Just guessing from far away, you might try some .535s with a .015" or thicker patch. You should also have a short starter because I doubt you'd be able to start the .535s at the muzzle with ease. Target shooters often start those patched balls at the muzzle with a small wooden mallet. Let me ask you, how much muzzleloading experience do you have?
