Last weekend, I had an opportunity to shoot a Model 12 that had been in the family for a pile of years. The serial number puts it as a 1916 gun, the stock was refinished some time back and looks super. It is a 30" full choke. The question is: the 13yd. pattern when shot with 1-1/8 ounce 8's shows a 6" diameter, fairly evenly distributed pattern (all individual pellet holes). If I were to shoot the same load at the same distance with my more modern Beretta with Optima chokes, I would have a fairly clean blast hole about 1" in diameter with fringe pellet holes around that.
The 35 yd patterns I shot with the Model 12 were more diffused than with my Beretta.
Is this a difference between the definition of a full choke over the years or has this barrel been "widened" by use?

ddrsuz.....Back in the M12 days "full" choke was a nominal .040" restriction shot through a .729 bore and the ammo was card and felt wads with naked shot. Winchester actually shot patterns at 40 yds and adjusted the choke on test barrels until they consistently shot a 70 percent pattern at 40 yds. A "full" choke today is considered to be .030 restriction and I don't hear much as to what the pattern percentage is supposed to be. Shooting a "modern" shell through the vintage M12 full choke barrel will probably yield pretty erratic results due to being overchoked.

Thanks guys, the gun and a vest was found in my uncle's garage or hall closet when we cleaned it out after he died. I remember the family having a .22 that my dad did not want in our house when we were little, but the 12 gauge was a mystery, known to the family only by story. When we found it after my uncle's death, it had probably not been shot for 40 years, now my nephew is shooting it for pheasant / ducks.

Since it is a 1916 gun, is there any reason to feel like it ought to only be shot occassionally and generally just kept as a trophy, or do you feel like you just blast away with it and if something breaks and you can't get the part, just make it an "nonworking" trophy of my grandfather at that time?
