Converting Shotgun to Centerfire???

its a .25-20 single shot rifle made on a cooey shotgun action, according to the seller it was a gunsmiths project. the barrel is a take off from a rifle, and its been fitted with william peeps. I debated mounting a 2.5-4x scope, but im doing pretty good with the peeps (right handed, left eye dominant, so i usually dont care for anything but glass). still need to get a sling for it. the gun is so small and light its a pleasure to pack around, and best of all, it still breaks down to the barrel, stock and forend without tools just like the origional shotguns.

ive only been shooting loads with unique in it so far, but have experiment with bullets in 75, 87 an 100 grain. its pretty versitile in loading, and can take a jacketed 60 grain bullet to nearly 2000fps (faster powder than what i have now), or with a little charge of unique (4.5gr) and a 100 grain bullet, its shockingly quiet and great for plinking.

Well to start you would need a new barrel ect........
Cost is the big why not... you need a shotgun, new parts, and a guy to put it all together. Your better off just buying a new rifle...IMHO:p
 
Some shotgun receivers are cast semisteel, or have huge diameter firing pins. A Cooey firing pin would be too large for many rifle cartridges. Might be OK with low pressure.
I added a .357 Maximum barrel to an H&R, works fine.
 
I think that 25 20 cooey remake is really neat, one day when i'm more adept at home gunsmithing i would like to try and build something like that. I can't imagine it would be overly complicated to fit together, with the right guide and some info. Would make a nice gun and cool project.

mine was bushed to a smaller hole and the pin turned down.

i got mine on the EE for about double what a cooey shotgun sells for. i was bored one night last year and went back like 15 pages on the sporting arms section. seen it posted but hadnt been bumped in months. I got lucky, the seller still had it and gave it to me for a very good price.

i want one in .22 hornet next.
 
Got ahold of the guy in alaska, he gave me a canadian dealer who is selling his products. the guy from alaska says the prices online are out of date and so are some of the calibers they are offering. he told me to check with Bruno for available calibers.

Canadian Dealer:

no website i can find.
 
For the price involved,and the potential risks (vast difference between shotgun and centrefire pressures),I will just buy another H&R/NEF firearm that I know is safe-and inexpensive
 
I have 2 of these "conversions" A thumhole stocked 22 hornet that was sleeved into 10" of 16 gauge barrel and receiver. It has folding leaf express sights and now a 6x scope. I can keep 5 under the inch at 75 yards no problem if I do my part.

The second was done on a cooey 12 gauge, same concept, bit more shotgun barrel. Took a barrel off a Win 94 with a busted tang on the receiver. put it in the lathe to fit the chamber of the shotgun and glassed it all in place with a couple of set screws. Awesome carbine, bit of recoild. has fibre optic Truglo sights on it. Both were registered with no questions - Cooey 840 calibre 30-30.
