The max "effective" range of the M2 HB MG was considered to be 2000 m when I was a tanker. The cal .50 MG is a really powerful round, [censored] near artillery.
I could not imagine hitting anything that far off with a Sharps. Sounds like Quigley Down Under. But I guess I am wrong. <img src="/ubbthreads/images/graemlins/doh.gif" alt="" />
