I wish I knew what a Bertuzzi is.
As I say, I find the cost of the gun to be on the smaller side of DG hunting cost out. I have mentioned before that I have improved my "range of use" of the doubles by procuring additional barrels in 06/06 or similar, so that they serve a broader use case domestically, in addition to 375+ for DG.
The point I badly made was there is a regular category of question here regarding "buy a double or hunt more." I don't think it is either or. Both work, the cost of the gun - for guided hunting - is a smaller part of the equation than many think, particularly these days, once you add it all up. For self guided hunting, a double is more likely crazy talk.
If the gun is part of the experience for you, and you love double shotguns, double rifles are just in the same vein. They are just better dopamine generators than an auto for me. I am fortunate - I have nearly every gun I could ask for except a Cosmi. The doubles get the nod most of the time. For me they are faster on target and easier to carry. They are fun to shoot. Still love the R8s in the smaller calibers.
