malfunctioned to dead last in a carbine match

[feets]

I have had good luck with the Hornady 100 gr short jacket bullets. They do not have a ball profile. My experience shows them to be more jam resistant due to the narrow point being harder to stop than the blunt nose of FMJ. The ogive allows the bullet to poke into the chamber a wee bit before making contact with the barrel. I call 'em squishies and it's obviously the bullet on the right.
The Remington soft point in the middle of the pic had a habit of catching it's nose on the beveled edge of the breech. It was almost perpendicular. Some of the jammed bullets showed part of the lead wiped away and the jacket would catch the bevel. It is shown in the center of the pic.
The 110 gr Hornady Varminter on the left was loaded just for grins. It is obviously too long to fit in a magazine but it seems fairly accurate when loaded by hand.

I think that magazines are the weak link in the weapon, just my opinion.

I agree Dave, and also the other things you said. The stamped mags were just meant to be a consumable part and thrown away and nobody would have fathomed they'd be used 65 years later. Even beyond the springs, the lip, boby etc can dent or deform. Who knows how many times a particular mag has been rammed home over the years. When I had my carbines I used to pick up a couple of new nags at about every show I went to.

My thought about the Korean mags are if they're even slightly out of spec from a USGI, and then the IJ is a slightly a different spec too, the effect could be exasperated, and all three Korean mags could malfunction the same.

Thanks for the lead. I'll talk to him about some magazines.

Happy to help, feets. I hope it works but regardless I'd want to try the simple things first before going inside your carbine again and possibly creating another problem.

It's good to have USGI mags anyway. Send John a PM, and I'll also email him and tell him you're doing so.

Good luck!

Well, John (kikokat) already sold all of his USGI mags. = Does anyone else here have a couple or know of any real ones?

[feets]

There are a few on the auction sites. Naturally, the cheap mags are rough. They're also of unknown condition.
I thought about getting a couple from Numrich too.

I never replaced the wiggly rear sight. It is all kinds of sloppy but seems to return close enough to center for me to shoot fairly well at 50 yards. That carbine match was a short range affair so sighting was not that critical.

That is one good thing about my Iver. I'm not going to hurt the value if I toss mismatched parts at it.

Can you just stake the rear sight, or iis it different from a T2 T3 M1 sight?

Hopefully someone here has some extras. I'd put a WTB up. It wouldn't hurt anything. I feel bad I don't have any left for you -
They had just been sitting there for years and John made a good offer for all of my extras and I had a big Dr bill to pay .

[feets]

Wow! It looks like you had a nice stash going. Sorry to hear it had to go away to cover expenses. That's never fun.
I'm not much of a magazine collector for any of my guns. I have 6 mags for my 1911 and I think that's kinda silly. I never planned on having more than 4 for the carbine. It looks like that is going to change now.

Is it possible that the lips spread out on the magazine and rounds were popping out under recoil?

I believe that's the ONLY way that I can see the 'double feed' you describe could occur. Get NOS USGI magazines. Forget the commercial and foreign wannabes. The real deal is not that expensive, there's still a bunch of them left out there and they work every time in a USGI spec carbine. I carry six new, fully loaded International Silver (IS) WWII mags (that fit and carry great in a USGI carbine ammo bandoleer) when I go to the range. I can't say you won't still have some problems because there are very few carbines left IMHO that are still fully within USGI tolerance specifications. But if you use new USGI mags you have taken one unknown factor out of the equation. Good luck.

I put an ad in the WTB area for some magazines.

My rear sight was staked. The peep is loose in the base and the base is loose in the dovetail. I haven't tried to stake it again. At this point it would just make a bigger mess to clean up when I replace the sight.
