.22lr Misfires

fabsroman · Mar 16, 2019

Got out with the 22lr yesterday and had about a 30% misfire rate with CCI Mini- Mag "signature" ammo that I bought back in 2013 or 2014. I cannot ever remember having this many misfires with my 10/22 ever.

This is the first of the 2013/2014 ammo that I have been shooting. I mostly use Mini-Mags in the 100 count boxes and then Velociraptors if I want to kill anything.

Almost all the rounds fired when I loaded them back into the gun. However, two rounds remained unfired after 3 attempts on them.

I am shooting a Ruger 10/22 with a Volquartsen fire control system in it. I have never had this problem before and it sure was frustrating. Anybody notice this type of issue with rimfire ammo from 2013/2014?

Has a bit of the firing pin broken off? Do you see a good imprint of the firing pin strike on the brass?

Rolo · Mar 16, 2019

I saw a article about that a while back. They claim that as 22 ammo gets older the primer in the rim deteriorates and misfires are a common problem. It was in relation to when people where stocking up when 22 ammo was scarce.

Dont remember where i read that.

I've had plenty of bad rounds with bulk .22lr, golden bullets in particular, but not usually with Mini-Mag.

Yep. There's a fix for it.

I have found that, if you keep .22 ammo too long, it 1) the report is less consistant 2) the brass tends to get crack and I have more FTF. I have noticed this both with Federal and Remington that I've had for over 10 years.

The only thing I have noticed with my CCI Mini Mags is that they are not consistent in the cold. They are better than other brands but, unless I keep a hand warmer in the box, you will hear the difference in the report and, my 1911 conversion will not cycle correctly.

Just went plinking with my son today, used a few pistol conversion kits. Used Winchester 555, and Federal 40 grn. Neither were flawless, They did go bang after a second trigger pull, or redo (reload in the mag) on a Glock after 30 seconds. It was about a 20% ftf for the group. My rifles eat the stuff with no ftf, and went bang every time, bolt or semi. I'm thinking the conversions are still breaking in, or light firing pin hits.

I have re angled and thinned most of my .22 firing pins based on an article I read some years ago. It may be located in rimfirecentral.com but I don't recall. It made a difference but didn't stop all misfires. I think it did make a bigger difference in my 1911 and AR15 conversions.

I am firing CCI from over 15 years ago, possibly more like 30, without any issues.

During that time period were a of ammunition shortages due to high demand. It's possible quality control was sacrificed to get product out.

John from MD · Mar 16, 2019

That could very well be as the ammo companies only had one line for rimfire. They may have let maintenance slip due to the high volume.

I remember reading a good article awhile back about the manufacture of 22LR ammunition. I can’t find it at present, but the gist of it was that 22 is actually fairly difficult to manufacture, and harder still to manufacture really well. The biggest challenge they claim is getting that priming compound into the rim, and it’s harder still to do it with ideal consistency. Kinda makes sense when you think about second strikes on a different part of the rim oftentimes igniting a cartridge that previously failed to fire. And if you’ve ever chronographed 22LR ammo, you’ll note that some brands do indeed tend to deviate less than others.

More like "That's GREAT!!!!!!!!!!!!!"

Yep, there is always a fix. Buy different/newer ammo, put a newer/stronger firing pin spring in it, file down the firing pin, put a completely new fire control in it, buy a completely new gun. That is the order I am going to go in to resolve this issue. Cannot have that many misfires, even if it is a .22lr.

There is always a fix. Only question is how much time/money is required.

That was part of my thinking. This ammo was definitely from the shortage era. Never would have bought the Landry Swamp People stuff if I did not think the sky was falling. lol

Going to try some ammo right off the shelf and see if I have the same problem. If not, I'll run through the "Choot em" ammo and say good riddance. If the problem continues with new ammo, then I delve further into this rabbit hole.

I found this to be true on packs of Remington Goldens. One box never allowed me to finish a mag without some type of interdiction. Finished it up and now running through some better stuff.

Mine was purchased during the run as well, so thinking it may be a common thing. CCI surprises me however. As I am sure it did you.

Try it in a different gun. If you don’t have a different .22, then go buy one.

For those interested, here’s the article I mentioned above regarding the many challenges inherent to manufacturing .22LR ammunition.

Thanks for that cool article. It’a a wonder that any of them actually fire.

I’ve often thought that the firing pin for the .22 should strike the rim in two or even 4 positions. Other than increasing the cost of the bolt and firing pin it seems like a reasonable solution to increasing the likelihood of primer ignition and would have the added benefit of creating a more uniform primer burn around the parameter of the rim which should also burn more powder consistently.
