Determining barrel looseness

[Tom]

Thanks Brian
The gun is tight, I am fitting a VH barrel To a DH receiver and had to sand down the sides of the lugs to get them in. Resulting in a very tight smooth joint. Only thing left is what you called off face, there is a .004 gap a little tighter at the top. I put a slice of electrical tape on the hook and it closed the gap right up. I'm just trying to figure out if that small of a gap is worth fooling with. I'll try the paper trick and see how it looks.

Thanks, Tom
