I received what was said to be two Brown Bess musket balls. The one on the right fits the description at .70”. The one on the left is .60”. These come from an arsenal in Nepal according to the supplier, and I do not doubt the authenticity of the balls. However, the description doesn’t fit the one that is .60”. What firearm would be in a British arsenal in Nepal that would fire a .60” ball? I like to label these and display for students. Any help is appreciated.
