M2 springfield misfires

[dokcop]

Thanks to all for the replies. No magic, I guess. Time to break out the good screwdrivers.

Herschel: I am under the impression that the 1922, the M1922m1 and the "stage one" M2 bolt, all without headspace adjustment, used very thin washers as shims between the rear bolt body/handle and the front bolt body to decrease excessive headspace. I stand to be corrected.

Regards, Dokcop

I just got two 1922's (M2) and had the same problem with both shooting certain ammo. Remington Match, Eley Match and Wolf all misfired quite frequently. One ammo that I tried did not have any misfires and that was Norma TAC 22. It is with regret that I report it is also very accurate. I regret that because everyone will start buying it and dry up the supply.

Now I did stumble upon a fix that may or may not have merit. I tightened and loosened the deflector knob on the back of the firing pin and found that had a big (positive) effect on the number of misfires. Not much, just a little - a few clicks. I did not get to spend much time determining which way was better, but it seems that they both wanted to be tightened - which neither was when I first started shooting them.

I did measure the rim thickness of the brands and found quite a bit of difference between the brands, but the Norma had the thinest rim.
