Duds: Apply here

I want your duds.

Actually and specifically I want you to record and track the number of dud .22 LR and .22 Magnum ammo you shoot and encounter this year. Rifle or pistol doesn't matter.

Yep a whole year.

Come March 1, 2013 I'd like to start getting reports in from you. No matter where you are in the world.

Not complicated, just keep a log of the date of the misfire, the manufacturer, the lot number from the side of the ammo box, the firearm you were using and maybe the temperature. If you encounter multiple misfires from a box that's fine (though you might want to check your hammer spring while you are at it).

It would also be wise to include the number of duds encountered from each range session with the amount you fired. This can look something like:

Number of rounds taken to range: 100
Number of rounds fired: 97
Number of mis-fires encountered: 3

I've begun a case study on the .22 in self-defense situations and while yes we all know that it's far from the perfect round you must also remember that in some places people rely on it for their life more than you think for bad situations. Trust me.

Now before you launch into why the .22 rimfire is this or that let me hold you up a moment. What I am looking for is mentioned above not a tirade for or against.

Look at it this way. You now have a perfectly good excuse to pack up your .22 and shoot more this year. If someone complains that you are shooting more than usual or you are spending too much time on the range you can smugly look at them and say "it's part of non-for profit international research."

I will do my best to help you shoulder this burden. It will be trying, but I shall succeed.

Well, there are plenty of duds in Washington D.C., but they are of a smaller caliber, I think.

Seriously though, if I can afford a conversion kit for my Glock at some point I'd be glad to chip in. I'll let you know if I'm successful.

If you're interested in real-world self-defense situations involving a .22 weapon, I've trained disabled and handicapped shooters for many years. Several of them have had to defend themselves against attack; and since many of them can't use a weapon with any recoil to speak of, due to physical limitations, they used a .22LR. I trained them to get the best out of it, and I'm pleased to report that they did - and they're all still with us. Some of their attackers aren't.

If you'd like to discuss this further, please drop me a line at my e-mail address (it's in my blog profile).

WV - 'precull' - does that mean we pre-cull the bad guys before we take out the really bad ones?


Odysseus said...

Not for or against, but I did once have someone I consider knowlegible about shooting tell me to not store rimfire ammo on it's side for long periods because the primer can concentrate on the "low" side meaning if you strike the "high" side it wouldn't fire.

I have personally had "bulk pack" 22 rounds fail to fire until I rotated them in the chamber of my revolver at witch point they did fire.

Considering that this could very well happen in a daily carried gun, it might be a valid argument against rim-fire for self defense.

I have had the same situation as Odysseus but after disassembling rounds found it to be not enough primer to begin with.

"after disassembling rounds found it to be not enough primer to begin with."

Just curious, but how do you disassemble a .22 round and check the priming safely? Do you just pull the bullet, dump the powder and use a micro-borescope to view inside?
My understanding of rimfire manufacturer is definitely limited, but I think the manfr'rs weigh the primed cartridges to check for proper priming quantity, but I could be wrong.

To Craig:
How I disassemble a .22 round to check primer:

Pry on bullet with pliers griping case with fingers.

Dump powder and shine in a dim light and see a ring of primer.

Dud rounds had only a partial ring of primer but didn't seem to have excess on one side. I only ever looked visualy.

A member of my range showed me this at our weekly .22 shoot a few years ago. Have checked about 6 rounds with same results. Next time I should try a scale also. Thanks.

Interesting. I'm glad you commented back on that.

I stopped shooting Remington ammo because in one brick I had more than fifty (that's one box+) of misfires. Some eventually fired off, but it was multiple attempts. Some never did go off.
That said, beginning March 1, I will keep track of all misfires from CCI Stinger and MiniMag, Federal (510's), and Blazer (CCI cheapies).
The majority will be shot with a Ruger MKII and the rest with 10-22 and Marlin SQ880. I'll keep track of which weapon had the problem(s) as well, if it interests you.
Thanks for the opportunity to help.
WV, if it matters, is 1995sitecong

Do you care about split cases or anything else unusual?

Matthew said...

@ Joe: interesting I was having problems with my Federal ammo which is what prompted this whole idea....well partially.

@ Anon: Absolutely.

Joe said...

I have a very low dud rate with the Federal and I shoot a lot of it both lead and copper plated bulk ammo. However I have 1 gun that does not like it at all. There are 3 reasons I can see for a high failure rate: A) Quality control issues. I believe a large amount of major brand bulk ammo is now manufactured on contract in eastern Europe. QC inspections may be limited or non-existent. It's cheap enough that normally no one really cares.
B)Head space. With 22 ammo, rim thickness determines head space. Bulk ammo can be a little iffy in this regard. This is the problem with my gun. Head space is a bit longer and the Federal bulk rim appears a little thinner. Changing ammo is normally the cure for this. Usually a better quality (more expensive) ammo will fix this. If your gun doesn't fire with CCI Mini-Mag it's probably time to see a gunsmith.
C)Last is firing pin protrusion. A burr or just a little dirt in the firing pin channel can reek havoc. Sometimes touching up the firing pin with a fine sharpening stone will fix the problem or just hosing out the firing pin channel with brake cleaner.

Do you want data on misfeeds as well? My M&P15-22 averages eating one about every/other magazine (nose up, very much like a stove-pipe, except in the mag feed lips.)

Glenn B said...

This will be an easy task with .22 magnum as I have never had a failure to fire with them. As for .22LR, I rarely get a dud now and again but will try to remember to keep count. I will also keep count of how many 22 rimfire rounds I shoot this year so, in the event there are no duds, you can figure that into your calculations.

All the best,

Windy Wilson said...

Interesting. I can't recall having duds, even with the Remington Thunderbolts, which have the execrable feature of not feeding in my Buckmark. I will keep track though. I think this is an interesting project.

I know I was supposed to wait, but I doubt I'll remember.
Only one so far Remington golden bullet HP bulk pack. Tried over a dozen times, turning the cartridge a bit clockwise each time. No good.

first dud of the year 1 round of cci plinking copper plated standard velocity out of box of 100 light strike? this was in a 90 year old Savage 40 .22 rest of it ran fine. Same rifle ate 200 rounds of cci a couple of months ago. I'm guessing bad primer. Was .22 Long Rifle.
