I guess they're pretty close - 20 ga 3" goes up to 1 and 1/4 oz shot load, and 12 ga 2.75" goes up to 1 and 1/2 oz load, so I guess the 12 ga will technically put more lead on target, but the pattern is gonna vary by gun, ammo type, and choke used. Thanks all. Reason I'm asking is I had planned on buying a 20 ga for upland birds, but there is a smokin deal on a 2.75" only 12 ga on page 49 of the current CDNN catalog - it's a closeout on a Verona/Bernardelli SX 80 IL, for $399 (regular $928) - oil finished checkered walnut, monte carlo stock, raised 9mm vent rib, 4 trulock extended chokes, Hi-Viz sight, Competition trigger, extended forcing cone. I could make either one work equally well for upland birds (with mild recoil), but if I loan my turkey shotgun to a buddy to take on a turkey hunt, and use this new one for backup turkey gun, I like to be able to smoke the gobblers with a lot of lead (tough critters), so I'm thinking of jumping on this 12 ga deal, as it will do everything the 20 ga will do, and a wee bit more, even when limited to 2.75" - which is why the price is so low, I'm sure. Nice looking gun - anyone know anything about these Veronas?
