"Barrel condition is going to determine if it will shoot... "
I respectfully disagree because in the case of my 1917 the barrel is horribly pitted yet it is extremely accurate. If you looked at the bore of my rifle you would think it couldn't hit the proverbial broad side of a barn, but it's a tackdriver. It's a JA 2 groove which from what I have read retains their ability to shoot well.
