I grabbed the wrong set of barrels when I cut the first ones. They were 30" barrels so I cut off 6", not 4. This set of barrels were 28". Cutting off 4" and the barrels are still almost touching. So, it is entirely possible to whack off 4" or so and still have muzzles touching. For the condition these damascus barrels were in, all 3 sets rang nice and clear and, from what I can see looking in the space, the barrels don't look that bad under the rib. I should remove the top ribs and have a good look.
