Glock 23 question

5mmgunguy
My son owns a Glock 23. We are relaoding for it. WW brass with Fed SP primers, 5 grains unique and 180 gr FMJ bullet. The load doesn't seem hot but about 3 out of 10 primers look like they got pierced. At least the dent from the firing pin is black inside. The others are all shiney and clean. What is going on? How do we address?

    I would try a different brand of primers, to see if makes a difference. My experience is that Federal primers are a lot more sensitive then other brands. In striker fired pistols like a Glock that a advantage as far as I'm concerned. In my experience Wolf and Winchester primers aren't nearly as sensitive as Federals.

    Are the primers flattened at all?...hold the questionable ones up to a light to see if they have been pierced...All of my Glocks hit the primer hard...

    Yes the primers are flattened. I have held them up to bright light, and I can't see any pin holes. That said though the primer is definitely black where the striker hit on three of them, while the others are bright and shiney where the striker hit the primer, so something is going on.

    I can't find Wolf or Winchester, how about Tula I have found some of them.

    Also found Remington and CCI, how about them?

    If you notice the glock firing pin is like a knife point not round like most firing pins. Do not use federal primers with a glock. CCI and Winchester work just fine. As said above Feds are real thin skined, where as CCI and Winchester are thicker and harder skined.

    Go ahead and try the CCI's and the others, I've loaded thousands of CCI's without a single problem in any of my striker fired guns. However, I don't own a glock. I'd say buy a pack of 100 of each of the ones you want to try. It'll only cost a couple bucks that way and you can narrow down which ones your gun likes. I'd copy the same exact load you're already using and load maybe 10 rounds of each using the different primers.

    5.0gr's is hot for a 180gr. Back off to about 4.3 and work up a little if you even need to..

    I prefer Universal over unique, especially in the 180gr range.

    Just start using CCI primers, not only do you typically find them cheaper, but they are harder. Federal primers are notoriously soft.

    If you handload, invest the $100 in a chronograph. It takes alot of the guess work out of things....

    Also make sure your not putting to tight of a crimp on your bullet. You want the least amount of crimp you can get away with.
