Question about Civil War Oddities?

Question

Can someone provide links to a webpage related to the following Civil War anomalies?

1. Musketballs fired by the opposing sides that apparently collided in midflight and fused together.

2. Muskets recovered from the battlefield with more than one load of powder and ball?

Answer 1

I heard about the first one on an episode of Mythbusters (episode 67). They concluded that it is "plausible" for the musketballs to fuse.
