I was looking at mid way USA web site and they have shilen stainless match unturned barrel blanks for a cheap price. Whats the deal with unturned blanks? Can you just polish them and chamber them like any other blank you buy? I was under the impression that after contouring a barrel they had to be relieved of stress? If i buy a unturned blank and have it turned, will it need stress relieved? If i have to have a barrel contoured it doesnt seem like much of a savings, after all i would have to pay my smith to turn it. Whats the scoop, why would you buy a barrel unturned? Thanks Lee
