Surprises me you don't have a 16. The perfect gauge for a SXS double IMO. 12 gauge SXS looks like a blunderbuss and 20's look like a cork gun.
Those who like'em seem to really like'em.
Probably would have liked'em had I been exposed. Just never went there.
Reloading for 3 is better than reloading for 4...
