Just got my NAA pug today along witg a couple others not related to the story. I grabbed a box of cci maxi mag fmj and everything was fine until around the 5 reload. I had 2 duds in one cylinder. I stopped after that.

Anyone with more knowledge on either this gun or this caliber wanna have a go at weather it was the ammo or the gun? Anyway to tell? I could see that the firing pin had hit the primer. It didnt look obviously or largely different then any of the spent casings. But i cant say weather or not there was a minor different. Lighting wasnt too good.

On a side note... i have shot everything from .22lr to. 44 mag and never shot a gun i didnt feel 100% comfortable with after the firdt shot... til i shot this little. 22 mag. Its got a hoge grip and still wants to pop outa my hand ( i have good grip on it and honestly i dont think it would jump out. But it sure feels like it. It does move up a bit after i fire it. I kept re gripping it after every shot or too) though it was fun after the first two cylinders. Until these two rounds. A dud is no biggie in a semi auto. But my lack of knowledge on the subject has me leary of pushing duds out of the cylinder of this thing. Especially when one was the last of 5 and i gotta take the pin out...

I bought my first .22 Mag in 1970 (Winchester 9422) and a second one in 1985 or so (Colt Scout).

And I can honestly say I have never had a misfire with Winchester or CCI .22 Mag since then, ever.

But I haven't bought any new .22 Mag ammo lately.

Still, an ammo related misfire with CCI anything is right up there with a Bigfoot capture in my experience.

As such, I would suspect the gun, not the ammo.

One sure way to tell is pull the bullets on the misfires with a pair of pliers, dump the powder, and look inside the case heads.
See if there is truly primer compound all the way around the rim, including under the FP dents.

If there is, your FP didn't hit it hard enough to set it off.

I usually remove a 22 misfire rotate it and reinsert it so the firing pin strikes another area and see what happens.

Did you rotate the case and have the firing pin hit it in a different spot?

Eman beat me to it.

I do not still have the two rounds so i cannor remove the bullwt. I dis not rotate the round to try and refire.

In the future i will consider either idea an option.

IMO: Pulling the bullet and checking to see if there is primer compound under the dent is a better method to isolate a gun or firing pin problem.

Sometimes primer compound falls out of one spot in the rim, or wasn't there to start with, and truly is a ammo problem.

But there is probably still primer compound around the rest of the rim.

So rotating it and getting it to fire the second try proves nothing about whether it is a gun or ammo related problem.

It just proves it went off the second try.

I had the same problem with a new FA Model 97 w/22 Mag cylinder. The ammo was okay (worked in a S&W 648). FA sent me a stronger hammer spring and all was well after that.

Maybe i should contact NAA. I will be sending it in to them in a mobth or so anyway for a 22lr conversion cylinder. Maybe we can kill two birds with one stone.

Every box of rimfire ammo I have ever seen contained at least a couple of duds. It's just the way mass produced rimfire is.

See, i have shot thousands and thousands of 22lr. From 50 round boxes of federal and remington. To the 500-550-555 round boxes of those brands and winchester. Shot plenty of cci and aquila too. And its been an extremely rare event for me to have a dud. And never two in a box. Even the bulk boxes.

2 in a box is totally unacceptable for any good brand of RF ammo.

Like I said, I have Never had a .22 Mag misfire in nearly 45 years in two different guns.

And I honestly can't recall ever having one in .22LR either using Super-X or CCI.

If you regularly get a 4% misfire rate with quality .22RF ammo, you have a gun problem.

I have never had a FTF in 22 mag. But I don't shoot huge quantities of it either.

Makes me suspect that it is a spring tension issue. But I wouldn't focus on that until you have shot it a bit more.

Thanks so far guys.

So i think next time i can hit the range i will try to get another box of ammo. Ideally a box of the same and a box of another. But beggars cant be choosers right now with ammo.

I will finish the box have and the other box(es) as well. See what miss firles from what box. Keep all duds for future investigation.

I need to do this before sending off for conversion cylinder so that if it is in fact the gun tjey may be able to fix it in one trip.

I would think 22 mag would be held to higher manufacturing tolerances than bulk 22lr.

I bought my first .22 mag in 74. It was my truck gun for decades. Never had a dud. Also had a ruger revolver - no duds. I've shot thousand of rounds with zero problems. I suspect it's your gun.

Same story here, but it was a NAA Black Widow that was sold as used to me at a gun shop. I contacted NAA via e-mail from their website and inquired. They sent me a new hammer spring. Just LOOKIN' at the springs when I got the old one out of the gun, it was easy to tell the spring was limp. I installed the new spring and no more worries, fires every round.

My advice, related this to NAA and they'll fix you up I'm betting. the spring installed easily with a pair of needle nose pliers.

I had 17 miss fires from 1,000 rounds of Rem. 40 grain soft point ammo but NEVER from CCI stuff.The miss fired rounds would NOT go bang in any of my guns.I fire quite a bit of .22 mag. ammo in my PMR 30 and marlin 922 mag. bolt gun.and also my Taurus Tracker convertible 4".I think I must have gotten a bad box of that Rem stuff but will never know as I dumped them all into an ammo box for storage.That's the last time I do that for obvious reasons.
