The Browning Double Auto was made at various times in three Models/Weights. The Standard steel receiver gun, the Twelvette with an alloy receiver and the Twentyweight with an alloy receiver and further reduced weight. The DA's are one of the best balanced semi-autos Browning has ever made. Very lively shotguns in the Twelvette and Twentyweight (particularly with plain barrels). DA's make great upland hunting shotguns. The DA's were made with Cylinder, Skeet, Improved Cylinder, Modified and Full fixed chokes (may have been made in more choke choices but these are the ones I have). It was made with plain barrels, vent-rib barrels and a unique solid rib with a recessed channel. Black and Grey colored receivers are the most common. However, the DA receivers were made in many other colors (including many that were only made in as experimental colors). A few 20 gauge experimental DA shotguns were made but the guns never went into production.
The DA was invented by Val Browning, son of John Browning.
About 67,000 were made in all. The gun has a cult following and they are very collectable in the unique colors. They are best used IMO in the uplands. As stated before, I don't use many magnum loads in mine as I don't want to tear them up. That trap model shown above has had many, many, thousands of rounds including some big ones ran through it. I do have a beat silver DA that sports a rifled slug bbl for deer. It kicks like a mule and I have yet to shoot it at an actual deer, maybe this year? They are very dependalbe and parts are still available. Art at www.artsgunshop.com can fix them. Black and Grey DA's can be had for $400-$600. One just sold in a LGS for $390 and was in average condition but was functional.
I bought one very cheap, with a skeet barrel and shot a 97 with it the very first time I used it. I almost didn't but it because the barrel was so thin but Dbl Auto talked me into it(It didn't take much urging). I've always been fond of 1100's and 390's but can understand why folks like the twelvette. Jackie B.
I bought a Trap model Twelvette in 1964.
I loved it, easy recoil, never failed, however, the "chrome" lined bbl rang like a bell after every shot, and the ejected hull almost always hit the shooter to my right square in his (or her) temple, did not make many friends that way.
Never had an auto-loader throw a spent hull as far as that Browning did.
Would have kept it if I could have found a shell catcher to fit that worked.
Sold it at a nice profit and bought a NM Garand. Shot a lot of DCM with it, but now I use the Garand once and a while at 3 gun shoots, don't win much but the roar and the clang of the enblock clip ejecting is a hoot. Love the look of disaproval from the piss-ant AR frame .223 shooters. Man up boys, take a little recoil, I think I need an M1A next.
