I'm planning a M-14 rebuild using a Norinco action. The 260 Rem cartridge is of interest and appealling to me for the end use of the rifle. Has anyone completed or know of a completion of a 260 Rem M-14?
Since the case is a necked down .308, Mag and action fit are of no issue. A typical 260 Rem load with 140 grain has close to the same muzzle velocity as a .308 150/155 grain load, I would expect pressures to be similar. My concern is gas flow for action operation with a smaller caliber.
Ideas/ opinions?
 
can you actually find someone to make an m14 spec barrel in 260 rem ?
I get asked at least, bare minimum 6 times a month about such conversions but the limiting factor has always been lack of a suitable barrel to try such fun with.

someone send me one (a barrel) that's ready made for this purpose and i'll build one for ya just for kicks.
 
I thought about this for about 4 or 5 years now. Never had enough dough to pick up the phone and order one. Enough money as in to reply " I don't care how much it costs, just turn me one" to their reluctance to do anything else than what's on the list.
 
It seems that even if you do have lots of cash the people involved in getting M14 barrels here in canada dont seem to care much. If anybody here is interested in a group import thing, I'm in.
 
"...gas flow for action operation with a smaller caliber..." Long ago, when M1A's were new, SA Inc. made 'em in .243 Win. So it can be done.
Like M14Doctor says, the trick will be finding a barrel. It'll be a cu$tom made barrel.
"...a group import thing..." Importing, in this case, will be the easy part. Nobody makes the barrels.
 
260 Rem M-14

Actually I'm planning to acquire a Blank from a local respected barrel maker and having a smith with experience in this area fit it. There shouldn't be too much mystery to it, the M-14 is just another action and a barrel fits in the end. As far as cost goes, the real loss is the barrel as the fitting to the M-14 action would require a gas vent that would render the barrel useless for any other purpose.
 
Making a M-14 barrel from a blank is a lot more complicated than making one for most other rifles. But if the 'smith has done it successfully before, then a .260 would certainly be do-able. The cost isn't going to be in the blank, its going to be in the machining and fitting.
Might be worth asking Kreiger if they would make up a 6.5mm M-14 barrel with a short .260 chamber. They already have M-14 barrels in production, and are set up to make all the various cuts unique to the M-14. And Kreiger exports, and there is a Kreiger importer.
 
I agree the cost is the fitting and likewise the cause of loss of the barrel if it doesn't work. The smith would do the fitting and chambering during the install so any rifled blank would work. I'm planning an 8.75 straight contour barrel with a custom gas block.
 
8.75 as in an 8 3/4" long barrel?
8.75:1 twist?
Is the custom gas block commercially available, or will it be a one-off?
 
all dimesions ..... and i mean all...... are measured using the gas port as zero..... your machinist will need to determine desired gas port size and location prior to commencing any other machining to the barrel. My suggestion would be to use a non chrome lined barrel and to undersize the gas port until it can be assembled and tested... and depending on results, open up the gas port a little at a time to achieve Bingo for .260

I would spend a couple dasys cruising the U.S. M14 forums and search for similar projects and info.
 
My mistake on dimensions, getting my job and interests all mixed up. 0.875 Diameter barrel, straight contour, 20 or 22 inches long finished, stainless.
The smith has completed M-14 projects and an Mini 14(mine) as well with documented success. I understand things in theory and by design but I'm not a machinist, I have my ideas of what I'd like...just hope they match with what can be done.
