Chamber adapters

[Kortsman]

Was browsing around gun broker and I came across something called a chamber adapter aka shotgun adaptor.

It's basically a hollow shotgun shell that allows you to shoot different caliber bullets from it. For example, you can load a 44 mag into the 20g shell and then shoot it. Not sure about the accuracy you'd get, looks fun. Anyone ever shot one?

seen some video of them on you tube and accuracy was ok at short distance but fell off real fast. depending on price it mite not be a bad thing to have one or two diff. cals for J.I.C.

So what happens to the bullet when you fire it? Do you have a .45 bouncing around inside a 12/20 ga barrel?
Looks like an accident waiting to happen

shotgun to shotgun ones in theory would be fine w/ any pellet shot
the 10ga to 20ga and 12 to 20 or .410 the same... also good for letting kid shoot it with smaller load..

would pass on any rifle or handgun round though..

I thought the same thing. All the testimonials on the manf. website said it was great for changing shotgun calibers. They didn't have one review about pistol calibers. Youtube had a few videos of people shooting them. Then I got to watching people shooting homemade zip guns... Crazy! Guys shooting 12g buckshot from two pieces of pipe. Thought about making one for about 2 seconds and then realized I value my hands too much!

Since the adapter is 2.75 inches long, and a most handgun calibers are going to be an inch or more shorter, I expect the adapter is rifled in the non-chamber section, giving it enough spin to fly straight out of the barrel without hitting it. Be cool if they could add a stepped down, longer barrel that would extend into the shotgun barrel, providing 6-10 inches of rifling.

2 3 /4" of rifling isn't going to be long enough to stabilize much, for any serious type of accuracy. say the rifling area was 2 1/2" with a twist rate of 1:10, 1 complete turn (revolution) in 10", that would be 1/4 turn/spin. it might be feasable for using a smaller shotgun guage/round in a larger guage gun. sounds gimmicky, not accurate and a waste of money to me. some quality shotguns have used full bbl insert sleeves for years that work well, but they are not cheap, and add wt.

here is a video of a guy shooting 44mag thru 22lr and also has a 9mm rifled insert. [youtube]http://youtu.be/3l4PBOQT1dg[/youtube]

a 44 caliber round thru a 22 caliber bore? sounds like a golf ball thru a garden hose. sure it's not the other way around.
