Tula Primers - First reaction

Over the weekend I built up 300 rounds of 9mm ammunition for random target practice. The next day over lunch I went down to the range to shoot the aforementioned targets. I wound up using 200 of them.Up until now I was exclusively using CCI primers since that's what I was able to get cheapest locally. This time I used the same recipe except with Tula primers. Tula is the same company that makes Wolf ammunition and primers. It's my understanding that Wolf and Tula are the same thing.The rest of the recipe is pretty plain for a mouse fart load in the X5: 4.2 grn of HP38/Winchester 231 and a 125 grn lead bullet loaded to an overall length of 1.150". I've shot several thousand rounds of exactly that with no issue. (I have made three squib loads very early on, but the process has been far better controlled since then.)I ran into two failure to fires at the range. Interestingly both caused the gun to be really hard to cycle the slide to eject the still live round. I don't know a reason for that though. In both cases the round seemed to fully chamber and everything went into battery just fine.I decided to do some forensics on one of these rounds to see if I screwed something up.The length is spot on. (Max is 1.169")Let's check the chambering:Again, the gauge I have that has a really tight chamber seems to accept the round just fine.Next up: the powder charge:I took the cartridge down to it's components and weighed out the powder. My scale is accurate to 0.05 grains. (Perspective: that is 0.0001 oz!) I spilled a tiny bit of the powder while getting it onto the scale. But let's ignore that. Even at 4.05 grains I'm still only 3.5% low which is well within acceptable tolerance for this type of load.The cartridge length is fine. It chambers. It has an acceptable powder charge.Next up: let's see if it was just a light strike. How? I'll load the now empty case (with primer) and try hitting it with the firing pin some more.A primer going off is loud. In an enclosed space it sounds kinda like a .22. I'm sure it's quieter, but it'll get your ears ringing.After checking, double checking and triple checking that I was dealing with a empty case without a bullet I loaded it into my Sig. Aiming in a safe direction I pulled the trigger."Click."I pulled it a dozen more times."Click."I can only conclude that this primer just wasn't meant to go off.Overall, at this point I'm not very impressed with these primers. There's a small chance I could have seated it a few thousandths deeper since they are harder to seat according to other reports on the internet. That being said, a dozen firing pin hits should have set off just about anything.I'll report back after some more work with this since I have plenty more of these primers to go.[smugmug url="http://photos.vec.com/hack/feed.mg?Type=gallery&Data=16022847_ETiY9&format=rss200" imagecount="100" start="1" num="100" thumbsize="Th" link="lightbox" captions="false" sort="true" window="true" smugmug="true" size="L"]
