Due to my increased attention towards the 7.92x33 and serious consideration of getting the equipment to swage my own copper jacketed bullets... What would be the difficulty rating to convert the m14 to 7.92x57?

This is just a thought and I havn't even got out the calipers to see if the bolt moves far enough to allow the 7.92x57 in there...
 
7.62 NATO = 7.62 X 51 ....
7.92 X 57 would be too long .

The conversion might work in a 30-06 Garand or a BM59, which is based on the longer Garand receiver,
but why?

If you want a semi auto in that caliber, the FN 49 rifles were available in 7.92 x 57.

Yeah I know the FN's are available but I have the m14...

I wonder if anyone would trade straight across m14 for FN...

I really like the m14, it seems to be a very simple rifle in comparison to other semi auto's and I like doing things differently than others... hence the cummins powered ford.

It appears that the total length of the x57 is 11mm longer than the .308, so it wouldn't fit without excessive modification... damn
 
IIRC, the M1A's from over 20 years ago.... a few were made up in .243 Win and 7mm-08 cartridges. That would have been a cool experiment, and so would a .260 Rem!
 
The second consideration with 7.92x51 would be if it was too wide to fit between the guides in the magazine?

I wonder what kind of load and setup could be worked up in a custom caliber like that, I think I'm getting kinda hot for the idea. I wonder who would make custom dies?
 
7.92 X 51???
Why NOT?
I thought about that a bit when I posted my original reply .... but you would need a MAJOR investment in 8 MM bullets to logically justifly the expense of rebarrreling an M14 for this wildcat.

but who says logic has to enter into this conversation?

If we don't limit ourselves to only the 7.92, we already have the factory cartridge 9 MM X 51 .... aka the .358 Winchester.

Which by the way, makes sense in an AR 10, where you could really extract some usefulness from the heavier bullets, loaded to higher velocitoies. The M14 has a rather narrow range for operating energy, and loading the wildcat cartridges short enough to fit the M14 mag inside OAL, plus opening up the gas system and dialling in the powder charges to allow for more powerful loads with bigger and MORE HEAVIER bullets, might get .... interesting.

But why not a .358 WIN M14 barrel right now??
A 200-grain soft point bullet at 2,500 fps, out of a reliable, tough, 5 shot semi auto 19" barreled M14 , sounds like the perfect hunting rifle for those who think the .308 is a bit too light for bear or moose.

Obunted is looking for orders for his 18 1/2" Kreiger SS M14 barrels in .308 WIN ... maybe you could talk him into adding an 8MM X 51 or a 9MM X 51 [ AKA .358 WIN ] barrel or two??
And wouldntthatbesumthin??

LAZ 1

I'm seriously thinking about investing into a swaging press to make my own 125grain 8mm copper jacketed bullets. It is only one or two extra dies, but the same consumables to make heavier and longer jacketed bullets.

So seeing as I will be making 7.92x33 for a bd44, it would seem reasonable to have a 7.92x51...

How much more difficult would it be to have kreiger do an 7.92x51 m14 barrel? Would I need to provide them with a drawing of my required chamber dimensions or would it be better to have them do the profile and chamber it myself in my lathe?

For that matter, how difficult would it be to lathe an m14 barrel from a blank 7.92 10:1? Do I require a milling machine as well?
 
If you favour the large slow route, rather than the light fast approach, you can start thinking about using your own cast lead (with copper gas checks) bullets. Then this idea really looks good.
