i know this has been discussed lots but i can't the search function to ever work properly for me. i'd like to build a .30-40 Krag double. either by sleeving a smoothbore or complete new barrel assembly. does anyone know which the proper actions are to start this on? i see brownells sells a book that guides you all the way through, and i will buy that someday. i remember someone mentioning it's best to have a cross bolt locking system. whats out there for reasonable priced actions? i know it won't be cheap, but i don't plan on buying a Rizzini or a Beretta as a starting platform.
 
My advice for you is check out nitroexpress. on the net. It has a huge section on building your own double rifle. Good luck.
 
I have that book. It describes the process in detail, but is not a set of plans.
Basically the original barrels are cut off to create a monoblock, and the new barrels are inserted into the bored out remains. Or, a new monoblock is made from scratch. A strong quality action is required.
 
Man blows off "wiener" with home made firearm.

June 29th 2009


Initial reports advise a man lost his genitals in an accident involving a homemade firearm in the early hours of June 28th 2009. WPS Greg McCoppy issued this statement: "This appears to be a horrific accident involving a possibly mentally challenged man, and a poorly crafted home made firearm." WPS officials advised criminal charges may be pending.

The man, who was apparently already in an unclothed state at the time of the accident, was found in the yard of his city home. He was holding a "margarine" container: inside were the mangled remains of his genitalia.
EMS first on scene are still being debriefed.

"Only a matter of time."

The man's father, who was present at the time nine media presented at the home, made this statement: "It was only a matter of time before something like this happened. I'm actually surprised it took this long." "All I heard was 'my wiener, my wiener!'" "At first I figured he got it caught in something again, but it turns out he lost it this time."

The man remains at Health Sciences Center in stable condition.

Was a fellow at the calgary gun show who was selling a couple of double rifles made by sleeving an old shotgun. They looked a bit unpolished and he admitted that the biggest problem was getting the point of impact from one barrel to the other anywhere close.

That's referred to as 'regulating' and you are right, it's reputed to be the most difficult part of the build.
 
There was a guy in, I belive, Ontario doing just this a few years ago. I remember reading a few stories on the subject.

As I best recollect, he used inserts in the barrels and left the origional shotgun barrels alone1
 
There were rifle full length adapters made in .45-70 and .38-55. Removable, secured by a nut at the muzzle.
A smith in the US, Bauska, iirc, would install a permanent sleeve in one barrel. Problem with sleeving, particularly both barrels, is weight. A sleeve could be smaller in diameter than the shotgun bore, to keep weight down. Perhaps one sleeve could be installed solidly in one barrel, the one in the other could be fixed solidly at the breech, but the muzzle could be floated, so that it could be adjusted for regulation, with bushes, shims, etc.
A .303 double would make a great hunting rifle.
The chap at Komoka ON (Nick Makinson?) used Browning 20ga guns to make up .470s. He added a Greener crossbolt type third lock.
 
Why not in a caliber a little more Canadian like a 303 British?

Also, it would save you having to change your handle to "kevin.30-40". :)


.

because they are basically the same cartridge, but the .30-40 has a better range of bullets for loading, and .308 barrels are cheaper and more plentiful then .311 tubes.

I once read of a fellow that built a custom .303 British with a .308" barrel. I think he said that all he had to do was change the resizing button on the 303 dies to the smaller .308".

Good idea!

I have a Browning BSS 20 Ga. with a set of 3030 barrels. A mono block was used with the barrels inserted and a short rib installed with the site. The 20 ga barrels still remain intact with the forearm. The rifle barrels have been shot and the gun hunted with. It shoots good. It was made in Sundridge On by Norm Hamm who has passed on. I can e-mail photos but can not get them to post. Perhaps some one else can.
