dominion primers

just switched over to Dominion primers and finding I`m getting a lot of primer ignition failures. Averaging 4-10 per 100 :(

I`m using a Vibra Prime to load the primers into tubes and reloading on a Dillon XL 650. Could it be the excess vibration that`s shaking something loose in the primers? I`ve been trying to pay attention to making sure the primers go in and are seated squarely, and I`ve been using my Grand Power X-Calibur with stock springs and recently detail stripped & cleaned. I don`t think it`s a light strike, as I`ll give them an extra couple of trigger pulls in DA before I give up and eject the dud round.

Those are light strikes, do you have any issues with Cci, s&b or Winchester primers in the same gun?
 
No problems with the 3,000 rounds I loaded first using CCI primers, and no problems running through ~5k rounds of factory (American Eagle, Blazer) and ~2k of commercial reloads from Custom Reloading Services. I'm going to bring out my stock Glock G17 to the next range trip and try a batch, see what happens. Will bring along some of my duds too and see if they may fire ok in the Glock.

wow - those are definitely much deeper strikes than mine. Maybe I'll retry these in my Glock G17 and my CZ SP01 Shadow. Both of those have the stock springs in them as well.

VanMan,
I'm using 3.3 grs. of Titegroup with 147grs Cam Pro bullets, Dominion primers out of my CZ Tac Sport.
It does look like your brass is getting light strikes.
Here's a pic of my fired brass.

I still cannot believe those idiots at Federal, Winchester, Remington, CCI, etc have failed and continue to fail to supply the voracious Canadian appetite for primers! What's wrong with these manufacturers that they would allow our Russian friends to almost completely take over the Canadian primer market?
Evidently the so-called "small potatoes" Canadian market is not important enough for these manufacturers to supply. But our Russian friends will. I say, BRING on the Russian primers, (and they're cheaper!) and BRING on the Russian POWDER!

a primer that goes off will always have a deeper hole because of what happens during the firing process. the only way to compare it with yours is to fire a primer only, no powder or bullet.

Could they be small rifle primers instead of pistol? Harder cups would make it seem like light strikes.
 
Didn`t know that, but I guess that makes sense. I`ll have to sort out some fired brass from my next range session and have a look.

I've used about 12,000 small and large pistol and never had a single dud. 9mm, 45 ACP, and 44 mag. Fired in 6 different guns with all sorts of differing spring configurations. The only issue with Dominion primers I've had is the SP are sometimes real tight in S+B brass, had to toss a few S+B range pickup cases.

Interestingly the Dominion LP primer in my Dan Wesson 44 has given me my best accuracy with a variety of powders, haven't tried it with 296 or H110 I've always used mag primers with those.
 
I dont have issues with them in my 1911s, but the shadows with super light springs in them for IPSC do seem the have light strikes. So I'd say good for practice ammo but I'd run something else for matches. They are so cheap compared to everything else a few light strikes doesnt bug me
 
Did some more testing, out of a batch of 100 - had 6 primers fail to go off. I also tried firing those 6 rounds in my Glock G17, but still no luck. I was going to pull these rounds apart to reuse the brass and bullets anyhow, and thought I'd see if I could manually set the primers off with a hammer and a nail (filed down the tip to round it off a bit). Had 1 go off, but the other 5 still didn't go off after repeated hits (was actually driving the supporting nails into the 2x4 so I had to use a couple of nails). Can anyone offer any insight into this? Am I somehow shaking loose the anvil when I'm using my vibra-prime to load the primer tubes? Or maybe repeated light strikes is shaking loose the anvil? Pics attached.

Here's the 6 rounds along with 3 casings were the primer did go off for reference.

Here's my super scientific testing method for trying to set off the primers with a hammer and nail

Here's a closeup of the casings after I beat on them a bit

Here's the primers I have. Anyone else have any experience with batch #61-13?

i have no proof, but my theory as to why a primer wont go off after several light strikes is that the primer cup pushes towards the anvil moving the small amount of priming compound away from the top of the anvil. once primer cup and anvil are touching there isn't anything left to set off the primer. what you can do is deprime those that didn't get set off after the hammer and nail test and pick out the anvil then check to see if there is any priming compound at all. if not, that's your answer otherwise it could be a few things.

my current batch ordered in march are lot # 64-13
 
I tried a 1000 and had 100 of the first 500 not go off, in several different guns, they are garbage!

I removed a dozen or so of the primers and set them on the vice and some would not even go off when hit with a 2 lb hammer, I gave the rest away and moved back to something reliable, not worth the hassel IMO.
 
Having had lots of experience with .22 rounds not going off, I can see that this could be happening. I'll try depriming a couple and see what they look like. I'll try to go easy to minimize the damage from the decapping pin.

don't think you'll be able to see if the anvil pushed through the priming compound, but worth i shot i suppose. also i just looked at your pictures again and would recommend using a shell holder to hold the case while trying to set off the primer instead of the head of a nail. if your wearing gloves and glasses you should be fine, but with the shell holder the explosion has somewhere to go vent vs being pushed up against the head of the nail. i've never set off a primer in that manner so i may be wrong but just a thought.
 
I've started using them, small pistol only so far. I've had a few FTF in my S&W Model 14 Target (they went off on a second strike) but other than that, no problems. I'll stick with Winchester in the Model 14 and 625 but use the Dominion for the rest. :)
