How often have you experienced a dud round of factory ammo?

[tacmedicp94]

nope

Never had a bad WWB round out of 500-700 rounds, had one dud in of Remington in 250 rounds. Haven't had a dud with any other various brands, but I shoot mainly WWB and Remington when it's on sale.

maybe 2-3 times, in over 20,000rds i would say in handguns.

though they don't occur often i train for malfunctions and the like often incase they do occur at anytime.

I have a 9mm Win Silvertip sitting on my head board to remind me that even the best quality self defense ammo can fail to fire. The primer on that one has been hit 5 times.

I've had a number of "duds" and other problems with factory ammo over the years.

Although I have no figures, I'm sure that taken into consideration the number of my reloads I've shot compared to the number of factory rounds I've shot, the reloads are more reliable than the factory ammo.
And the primers and new cases used in reloading that fail are also "factory".

I've had at least three duds per box of 550 federal bulk 22lr ammo. The duds usually go of, but with very little pressure. I've also had a couple of Blazer Brass 45's not go off at all.

I used to buy a lot of Sellier & Bellot ammo in 9mm and expect at least one dud in every box.

I finally woke up and quit using it.

 

[tblt]

never but still only use the good stuff for self defence

One dud recently in a box of WBB.

 

[jdorian]

Never had an issue yet, other than issues with the gun itself.

Same applies to some 8mm Turk WWIII ammo. If it doesn't fire we hold the weapon on target and count to 10 before we flinch.

Did I sleep through WWIII? Who won... comrade?

I had some duds in one brick of Winchester 'Wildcat' 22 LR 25 years ago or so.

Never on anything else; shotgun, center fire rifle or pistol or any other 22s.

A cartridge has 4 components: case, bullet, propellent, and primer. The case and bullet need to be of an exact size or else it will cause a jam. The propellent must be appropriate for the bullet weight. The primer must go off when struck and ignite the propellent.

That's a lot to go wrong, but rarely does it seem to happen that a malfunction occur and the ammo is to blame. At least for me and those I shoot with, I've only seen rimfire and really old surplus centerfire ammo cause a malfunction. The surplus ammo was Serbian or Russian 7.62x54r and showed some corrosion.

As for the ammo firing at a consistent muzzle velocity, that's another story. I'm sure that varies quite a bit. Perhaps it's the primers that have seen the greatest advancement in quality control across the industry.

Even rimfire. I remember back when I started shooting in the early 90s, which wasn't that long ago, I would have a pile of unfired rimfire cartridges at my feet. I used a Marlin .22 LR rifle, so there are more variables than the ammo, but I rarely have rimfire ammo fail with a Ruger 10/22 or CZ 452. I've fired over 10,000 rounds of .22 LR between those two rifles. Out of that 10,000 rounds, I've had maybe 3 fail to fire.

never had a dud or failure to fire, even when using factory reloads.
