What are your thoughts on the idea of getting shotgun barrels made at the same time my double rifle is being made? The idea of a matched set is appealing; the rifle on order is a Merkel 140, and Merkel offer the option of 20 gauge matched barrels if made at the same time as the rifle barrels (9.3x74R).

I already have a 12 gauge SxS shotgun (not Merkel - I'm not rich!), so 20 gauge would be a nice addition. What chokes to you recommend, for general use, mainly clay target, but a bit of field work, as well?

PS my shotgun skills are at the novice level.
