North American Arms .22 Mag Problems

[Jabr0ney]

So today at the gun show i bought a brand new naa mini .22 mag with the .22lr cylinder with it. I went to the range right afterwards.

I used CCI for both magnum and lr, but the magnums were the +v 2200 fps ones.

I had no issues at all shooting the 22lr. Went through about 40-50 rounds, no issues.

When i got to the 22 magnums, i encountered some misfires. And it wasn't just now and then. Almost every time i stepped up to range, out of the 5 shots, one ore two wouldn't go off. Usually they would go off with the second try but one or two took 3 tries for them to fire. None were duds. Also i notices that when dropping the cartridges into the cylinder, there's one slot that the cartridge doesn't just drop in all the way, i have to press it down for the last few millimeters. Also when the magnum cylinder is loaded, its a lot harder to get into the gun. With the LR cylinder loaded, it slides right into its spot, also all of the rounds drop in.

Anyone else experience this? Do you guys think it was the ammo? Or is the striking pin not hitting hard enough? I didn't think it was the since all of the LR rounds shot perfectly. Any help is appreciated!

EDIT: This is the ammo that was misfiring:

My BW misfires with Hornady and occasionally with Winchester, but CCI maximag fires 100 percent. It has never misfired a maximag in 400 or so rounds. Seems to be a might picky, but good thing, it's very accurate with maximags and not so much with the others, so I'm happy with it. I just buy CCI for it.

One clue is that it is hard to chamber a round.

Also i notices that when dropping the cartridges into the cylinder, there's one slot that the cartridge doesn't just drop in all the way, i have to press it down for the last few millimeters.

Either the chambers are dirty, fouled with oil or preservatives, or are simply out of spec. What may be happening is the rims are a tiny of a fraction of a millimeter from being fully seated, and they simply move forward when hit by the firing pin, cushioning its blow and causing a misfire.

I'll try giving it a good cleaning and shooting it once more before I make a decision.

Hey jframe how long did the whole repair process take?

How old is this ammo? Scrub the cylinders and barrel with a brass brush.

I'm trying to recall -- but I believe NAA has a policy of getting the gun back to you something like 7 or 10 days after they receive it (something like that). Whatever it was, my recollection is that the time frame was amazingly quick. Either a phone call or email to Justin, their head gunsmith for mini-revolvers, yields an account code you use to UPS the firearm to NAA.

Just to clarify one thing -- before I sent my guns back to NAA, I cleaned them thoroughly before doing one last range test, just to confirm that double strikes were still occurring, and that it was not because debris was keeping the cartridges from seating securely enough.

Had an early Earl sample here briefly that showed erratic magnum ignition.
