A friend has a beautiful unfired like new Austin Halleck .50 percussion Mountain rifle he is wanting to sell. They were originally located in Weston Missouri and later moved to Provo Utah where this one was made. I think due to lower priced competition and some quality issues they went out of business in 2006. Info I have read mentions they were on the high-end price point compared to other factory-made rifles they competed against. This one has a 32" barrel with a 1-28" twist with barrel and hardware browned. Does anyone have any experience or info on this?
