its not what you think, its just 2 rifles bolted together to make a SXS rifle


This thread may be in the wrong section as its rimfire but its also a sporting rifle. So, mods can feel free to move it if they wish.

For a while now I’ve wanted a really small impractical rifle chambered in something that would be most likely in a rook rifle. Some silly old little black power case. But having the million projects on the go I didn’t want to really spend any money on this build. So, I used parts that I had laying around. It’s chambered in 22 short I had 2 rimfire barrels sitting on the shelf so I used them.
I put way more work into this then I expected. Fitting the hand made parts is where the time is used up. The machining is the fastest part of it.

I made the barrels from old savage 22 take offs. I made 6 springs for the receivers, longer pins, both extractors, fit them all, set headspace, made firing pins, made the rib, had the sights sitting around already. Soldered the rib on with lead free plumbing solder (5% silver)

The barrels are 18.5” long the LOP is going to be 13” and the OAL will be 32”. It does have some weight to it id assume around 7 pounds when done.

Its easier than it looks to fire both barrels while aiming. The triggers are side by side opposed to front and back. You can see in the video how I put my finger through them both to fire them, if there was a lot of recoil, I could see it not working well.

You will notice one major fault in the barrels. It was late and I was rushing so not thinking, I made 2 left side barrels. I wasn’t sure how to continue, then I just said frig it, I’m making universal barrels and ill see what one fits what receiver the best. So the barrels have flats on the out sides of them.

The stock wood is from a big walnut that blew over here 2 years ago, the thread linked below is a thread on cutting the blanks from the tree.

It ended up taking a lot longer than I had assumed it would but It didn’t use any funds so it didn’t take away from my other projects.

Mechanically the rifle is done, now it needs the wood finished and some bluing to happen

ill have to regulate the barrels with the muzzles. right now with the gun in a vice both barrels hit a 8x11 piece of paper at 15 yards. im not sure if they are crossing each other or both in line but i feel i can make it work by altering the crown by trail and error



If you click the last pic it turns into a video of it cocking and dry firing

The receivers are two Remington no6

The rib and rear sight riser were made from a rusty piece of 2x3x1/4" angle iron I found out back. And it was only 17 3/4" long so the rib doesn't come to the end of the barrels.

What you have done is not likely something that I would try to do! But your comment about "regulating" I found interesting - that you intend to do that by altering the crown? - I presume that your intent is to alter the angular relationship between the crown and the bore centre-line? I know a "crookedly done" crown will throw wild - I guess that I have never considered to do that on purpose - to get the bullet headed to where you want - there was a video apparently from H&H where the guy was soldering and re-soldering the barrels - using various shims and wires - to re-align the bores to get the thing to put both Left and Right bullet at the same place. If you can figure out how to deliberately mis-align the crown, that may be an easier solution? - it might also have implications for setting up a rifle for extreme long range?
 
maybe shine two strong pointer lasers down the bore and see where they hit the paper… compare to target shot with live ammo and adjust barrels with the lasers to indicate approx where live rounds will hit .. just a thought
 
Very interesting. It appears the pulling of the triggers might be tricky. I don't have the talent/skill and patience to conduct such project. Kudos to you! I love sxs double rifles and shotguns, I'll purchase them instead.

Grinding the crowns is a bush way of regulating doubles, used by some of the lower end makers in the recent past. What you’re doing is dishing the crown one way or another, to vent more gas in that direction just as the bullet clears the crown. To my understanding having never attempted it, the side you relieve of the crown is the side you steer the bullet impact towards. As the bullet clears the barrel, there will be a brief moment where the pressure is higher on the base on the side with the higher crown, and the relief grinding you did to the other side relieves some pressure, altering the bullets’ path that slightly to that direction. It seems a totally feasible solution for a project like this, where you probably don’t want to spend a week soldering, and resoldering on the range.
 
Thanks guys I'm pretty excited about it.its chambered in 22 short so I'm not actually sure what I'll do with it other then look at it and shoot targets with it but I'm looking to get it finished up pretty soon I hope to get the fore stock finished tomorrow. I'll get some pics up when I do.

And Ardent, yup I have seen them and could only imagine being able to buy a rifle at that cost. I'm damn sure it would be a fine rile to carry in the woods though.

Potashminer, Ardent explained it perfectly. And with your comment about long range I have a feeling this process would be more so done with rifles regulated at 50-100m. Far from long range. It's kind of a hack way to do it but I'm only trying to regulate my barrels to 30' since it's chambered in 22 short. I am going to use the cci "target" 1080fps 29gr ammo to regulate with.
