What size round ball for 50 cal muzzleloader?

It depends on the make and model of a muzzleloader. For example, a .50 caliber Thompson Center muzzleloader would require a round ball that is .490-.495 inches in diameter, while a .54 caliber CVA muzzleloader would require a round ball that is .525 inches in diameter.

There isn’t a definitive answer to this question since there are so many different factors that can affect the size of the round ball that is best for a 50 cal muzzleloader. Some factors you’ll want to consider include the weight and type of powder used, the barrel length, and the intended use for the muzzleloader. That said, a good general rule of thumb is to use a round ball that is about .490″ in diameter.

Several different factors will determine the size of the round ball you need for your 50-cal muzzleloader. The most important factor is the diameter of your barrel. Other factors to consider include the weight and composition of your projectile, as well as the type of powder you are using.
