I am about to order a Pac-Nor prefit barrel and need a fin contur. Anyone that know what contour that SSK use on their #1 in 577NE? or other contour that should fit fine? Diesel Dude- what did you use?

When I talk to the gunsmith Iwill ask what contour the barrel is that he installed on my 577.

Casey says the minimum of a countour #7... bout a 6.5 shilen.
