    Port pressure too high; would bend op rods.

    Might work if your gunsmith incorporated an adjustable gas valve. I've heard of similar conversions.

    you could make it work, with enough time and $ of course

    Thank you, people. Sounds to expensive for me. Anybody have any idea of ballpark cost??

    Okay- I'm confused. The M1 Garand is designed to operate at 30-06 pressure levels, in particular the pressure in the barrel just prior to the bullet exiting. So if the barrel was reamed .015 we now increase the bore from .300" to .330". The useable bullets increase from 150-200 grains to 200=250 grains.

    So how does this change in bore diameter and bullet weight change the pressure as the bullet approaches the muzzle? Seems to me it would be a function of the powder type/load in combination with the bullet weight and sectional density, more so than the cartridge change.

    Well I guess anything can be done with enough time and money, but that would be adulterating a Garand. That's bad juju man!

    This is the concept designed and released at the 2006 SHOT Show:

    .458 WM Garand

    McCann Industries is a family owned business that has been operating in the same location since 1968. Originally opened as a Retail Gun and Sporting Store, it has evolved into a firearms accurizing, repair and reconditioning shop second to none in Washington State. We have also increased our general machine shop capabilities over the past 20 years. We are a complete full service machine shop, offering specialized work and production runs. Our work has been featured in numerous gun and rifle magazines. We take great pride in our prototype designs quality parts fabrication and craftsmanship.

    In the 62 years since the M1 Garand gas operated rifles inception, many people have tried to substantially improve it's performance... most have failed. Jim Jones and Richard McCann of McCann Industries have successfully met this challenge. There are so many improvements to this rifle that it's hard to believe the fabled Garand could receive such a face lift.

    Well, for all those in doubt, here is a quote from Hatcher's notebook. "In trying to determine the ultimate strength of the gun, Mr. Garand built up progressively higher proof loads in increments of 5,000 ft. lbs. pressure, from the regular proof load of 70,000 lbs. to the extreme figure of 120,000 lbs. per square inch. At this later figure, cracked left lugs on the bolt began to be encountered. A gun in which the bolt had the left lug cracked by one of these excessive high pressure overloads was then fired an endurance test of 5,000 rounds of service ammunition, using the cracked bolt, which showed no further deterioration. The US M1 rifle thus has perhaps the strongest action of any military shoulder rifle in existence at this time." Do you still doubt?

    The way that McCann and Jones have manipulated the entire mechanism is simply genius. The exact dimensions of the adjustable gas system, gas cylinder, OP rod and feed mechanism are proprietary. The barrels used are Douglas premium. All rifles are glass bedded with new stocks and trigger jobs to N/M specs. If this does not answer all your questions, please ask. The fit, the finish, and machine work are all first class. This is truly a firearm that can be handed down through generations.

    MCCANN INDUSTRIES WILL ASSEMBLE ALL PARTS AND TEST FIRE

    Best.

    I saw an article about a gunsmith with a small pecker who coverted
    m-1 carbine to 50 AE
    m-14 and m-1 to .338 win mag
    and guess what?
    the guy testing them broke the carbine (at the stock) in 9 shots and the m-1 in a magaizne load or so
    these were much siller conversions though

    There was talk on falfiles.com about a garand in 8mm mauser... and a FAL in a larger cal as well... 358 win?

    the Garand has been converted into .338 Win Mag which operates at much higher pressures than the a necked-up .30-'06.

    and, as pointed out above, has even been rechambered for the mighty .458. I don't see a problem with it given the right parts and expertise.

    30-06 would take down a bear wouldnt it?

    nononsense,

    WOW!...that is some GOOD juju! Pretty cool what can happen when someone takes their skill and applies it to the gun world.

    If I remember right the FN 49 ran a string of calibers and it was designed to be able to take the very hot Turk ammo by simply adjusting the gas port. there should be no reason that with some modifications an M1 action with the corrected gas flow couldn't be any caliber you wanted.

    I would think so. The .30-06 (properly loaded and with the right shot placement) would be potent medicine for all but the biggest North American bears and moose, IMO.

    I was interested in the heavier bullet.

    No objections to the '06 - kinda looking for something different.
