M305 re-chamber feasible?

Thanks for the comments guys. Glad to have .45ACP weigh in, looks like you have given this a lot more thought than me.

I think the .338 federal is designed for throwing 200-225 grainers at close to 35 whelen velocities from a short action. Probably from a platform restricted in Canada. If we want to get in on the lead slanging our options are pretty limited.

I own and reload a 338 magnum. Would also be interesting to see who the federal handles cast bullets. Seems a bit like marketing spin on a .358 but there is more bullet variety in .338 than .358.

That's kind of the same thought train I am on. Pretty sure it should work out pretty well, if (big IF) I can get the barrel......

I wonder if a guy could order up a kreiger or criterion M1A tube in 338 or 358 and if so how much would it cost?....... A guy doesn't need 2 kidneys does he?

Well.... I've been thinking of ordering a .338F blank and just making the barrel myself. I'm not a machinist by trade but I do have the lathe and mill needed to get er done.
Might give it a go this winter if I can pry myself away from the ice fishin LOL
 
Damn you guys bringin up this topic again hahaha
So last night we were sittin around in the shop discussing this .338F M14 barrel thing. The machinist helping us set up our machines had a look at the medium contour krieger stainless 22" I have in reserve.
This is what he told me....
If he were to take it and copy it exactly, from measuring to finished, with a short cut chamber, with me supplying blank, reamer ect... The first one would cost me about 2500 in shop time @ 85.00 an hour.
Add another 1500 to 2000 if I wanted it programmed to CNC.
So one gets an idea of why no canadian outfits have done it. Our market isn't big enuff to make it a worthy , and more importantly, profittable product to pursue.
 
^yikes

Looks like the garand platform can be re barreled in 35 cal. Would probably require parts we can't obtain here I guess?

I figured it would be close to $2000..... But $2500 is pretty steep. Add in taxes etc too!

I still think the most cost,effective way of doing a 338, or 358 build is a re-bore job, if a guy can find someone will to take on the task..... I figure that would be close to a G-note....

Talk about internet points if a guy gets it done! lol

Would .338 Federal have higher gas port pressure than .308? The M-14 gas system is a cut off and expansion type, so it is self compensating. Same cartridge head size, similar pressure levels, so back thrust on the bolt would not be an issue.
Does the reborer know that the bore is chromed?

It would have lower gas port pressure than the 308 by about 20%, by virtue of the larger bore and resulting higher expansion ratio. If not enough gas was being introduced into the gas port, a vent hole about 10% larger in diameter should mitigate that.

No he figured all in, pay in cash, about 2500 based on 85 an hour. I would think that's reasonable considering the measuring, lathe work and mill set up/machining.
He figured 20 to 30 actual hands on hours from start to finish. The fellow in question is a master machinist, having owned and operated his shop for over 30 years before retiring.
Regardless, I'm not about to pay that and once my rusty lathe and mill skills are all back up to snuff I'll just try and make one myself LOL what's the worst that can happen? ;)
