I just moved to a new state for a job I work now on an old military base. I was told by a fellow officer that if I go down to the bay there are thousands of old 45-70 lead rounds in the water this was area was a military base back in the 1800 when 45-70 was issued. My question is would this old lead be any good for casting? I'm looking at starting to cast 45ACP and thought this old 45-70 lead might be a good start?
