Though I have experience with various double rifles, I have next to no experience or knowledge of paradox like guns, and bore (gauge) guns, so I would like to ask a few questions: 1. If a gauge gun, in any gauge, is rifled full length, it is considered a bore or gauge rifle, is it not? If similar gun is rifles only partially at muzzles, it is considered a paradox or similar term used by various makers, correct? In a given gauge, such as 12 ga., are bullet weights heavier for the bore or gauge rifles than for the paradox and similar guns? What is the bullet weight used in the various paradox like guns, in 12 gauge? I saw a lancaster paradox like gun, shooting a 750 gr. bullet, so is that about the average weight for paradox like guns of 12 ga?
