Congratulations on your fine new double.

I think a set of shotgun barrels is a great way to really get to know ones double rifle as it is possible to shoot many thousands of shotgun shells in a hunting career but how many of us, except maybe NE450No2 ever even shoot a thousand rounds through our doubles. And if we did we are wearing the "old girls" out. I wish I could get a set of shotgun barrels for one of mine and have! Unfortunately it will not be a side by side but an under and over.
