I'll give another +1 to Jim Briggs at Northland Shooters Supply. Not mentioned so far is that Jim stocks a wide assortment of barrels: mfgs., lengths, contours, chamberings, material, grade and shank sizes. For example, I shoot F-Open with a 7SAUM. Not necessarily a common chambering, in combination with my barrels other specs. Saw my barrel was "cooked" this past Sunday. Called Jim on Monday, "I need a Criterion , 7SAUM, 30", large shank, stainless steel, bull contour barrel". It will be here tomorrow, 1 week from when I called! I had thought my barrel might have to be made to order, a 10-12 week wait. Nope, in stock. That right there saved my season. Priceless!! BTW, he had a variety of other 7SAUM's in stock, too.
