I just took delivery on a early 1960s Merkel 203 and noticed that the barrels are stamped .719".

Am I correct in assuming choke constrictions are relative to the individual gun's bore diameter? So if this Merkel is choked IC/Mod, the muzzles openings should be .709" and .699", while on a "standard" .729 12 gauge, those openings would be .719" and .709"?


Such a long, long time to be gone, and a short time to be there.
