My rifle was regulated without the scope. With the scope it shoot just fine.
I would forget about 26" bbls.

My Chapuis is the basic UGEX.

If I had it to do all over again I would have bought a little higher grade, still with color cased hardened reciever, no animal engraving I prefer scroll, nicer piece of wood and an extra set of bbls in 20 ga.

However it MUST have a scope.

A scope makes the 9,3 double the equal to any scoped 9,3x62 or 375 H&H.
