    The grand take a special powder suitable for it's gas action. Look in your reload books for recommend powder or over on the reloading threads.

    I used Win 748 and I had asked on the reloading portion before hand about using it for Garand loads. The guys over there said it would be perfectly fine w/ this powder.


    As far as the peening goes, I'll look into it but I may not bother considering the bore is so worn one out of three shots is not even on the 3x5 target (at 50 yards).

    I already bought a new used barrel that still has a shiney bore.

    Now I'm not so sure that I'd have the same problem w/ the gas cover covering the hole w/ the new barrel. I slid the gas cover over the new barrel and it does not slide down as far as it does on the old barrel. I could actually still see the gas port w/ the gas cover on the new barrel. On the old barrel the gas hole was completely covered. I even measured the visible groove that is showing on the barrel from the gas cover (as it was on the barrel). The groove was only showing less than half of 1mm on the old barrel. The new one had 1mm of the groove exposed.

    LMK what yall think

    If you have a barrel and someone competent in rebarreling a M1 Garand then obviously it can't hurt to rebarrel. I have several take off barrels lying around. One problem with a used barrel is they don't always like to easily index correctly. That can be a headache. Also whoever does the work will need the correct tools to rebarrel a M1 Garand.

    If you scroll down the link I left for peening you will see where they get into the gap between the forward handguards and the gas cylinder. That may be of some help to you.

    Thats why it was suggested to peen the splines on the barrel so the "Gas Cylinder" sets where it should. Its not unususl
    Was trying to help you with the barrel you have. If you are going to change it anyways why bother
    Hopefully you gauged the other barrel you are thinking of useing for replacement? Just beacuse its shiney doesnt mean the throat or muzzle isnt worn

    Thanks guys. The barrel I bought does have a shiney bore and here are the specs given by the seller TE=5.5 and MW=2. Not a perfect brand new rifle but I'm just hoping to get decent groups. It's not even for competetion, I just want somthing that looks good, shoots good and works. I plan on changing the stock too. And of course a reparkerizing job.

    Thanks

    My .02 is that on my rebuilt M1:
    A. Had a cracked gas plug
    B. Had a new barrel, spring and stock installed. The stock rubbed the op rod just forward of the cutout in the stock and the spring had to have coils clipped one at a time until it cycled reliably. Total of three removed.
    Now it runs and shoots like a champ!

    You may notice groups shrink after peening your splines too.
