hello engineering101,
I have received your message, thank you. My wife's cousin is married to a chap called Metcalf!!. I only shoot/stalk to close quarters, anything from 50 -120 yards, the land I shoot over does not lend itself to varmint style shooting, that said I have shot foxes to about 200-300 yards, but compared to some of the videoes I have watched that is on it spitting distance!!
keep well patrickt
