Trouble With Primers

[Gunsrruss]

Back during the shortage I scored on 5,000 small rifle match primers from Federal. Now I haven't ever had this problem before, but all the AR's I have do this. When the firing pin strikes the primer sometimes it penetrates or pulls pieces of the primer out ,or it gouges them real bad. I have cleaned small pieces of the primers out of the bolt it's self. It will even pull the primers out of the primer pocket. Now the whole 5,000 did not do this. Only the last two box's of a thousand. I loaded up 50 rnds today of CCI41 to test in the morning. I was hoping it was the gun, but now that it is looking more and more like the primers I'm disturbed, you see I have 800 rounds loaded with these primers. Has anyone else experienced this problem???

If it's happening in multiple rifles, then my first guess is that the rounds are too hot. Have you tried lowering the charge and seeing if it still happens?

Federal primers have a reputation for being softer and more sensitive than average, and the CCI military primers are specifically designed to be hard and tough. I agree with XDRox, your loads might be a bit hot. What is the load you are shooting? You should also reduce the powder charge and work back up when changing primers.

Did you check your firing pin? Is the tip still uniform and round?

And if you HAVE to pull down 800 rounds, I'd invest in one of these: http://www.hornady.com/store/Cam-Loc...Puller-1-Each/

I think I'd invest in a .223 bolt gun instead.

I'm not sure that blown primers are any more fun in a bolt gun than an AR15....

I ask only as a novice reloader.

Could the ambient temperature, a hot day, have any effect on rounds and over pressure?

Interested to find out finale verdict on the primer problem.

Possible but not likely. Certain powders can be temperature sensitive, but it's rare.

If the rounds are too hot then I wouldn't shoot them in any gun, they should be pulled.

primer

soft cup on primers use a cci militaty type m1a's will do the same they should shoot fine in a bolt gun

To Rap this up

I figured it out on the way to San Diego yesterday. I'm using different brass LC, and upped my load by .2gr. So the first guy was right I have hot loads. So I loaded up 5 different loads and will test them in the morning. Thanks all for your imput

If that doesn't pan out check firing pin protrusion, and then have the firing pin diameter and hole diameter checked. I use bushed firing pins in all my .223 rifles, come to think of it I have all my firing pins bushed and ground to diameter no matter the cartridge. Nothing worse than having a firing pin stuck forward in a semiauto from primer debris and have it FA on you.

The Remington 7-1/2BR primer was made just for the .223 Remington because of primer problems.

Hot loads

Yes,they are hot loads. I loaded the first five .2gr lower and they were fine. Then the second and third set at 24.4 and 24.3. All fired and the primers looked great. Problem fixed. I think I will stick with 24.4gr from now on of WCC 846...BLC-2. I've decided to take the 800rds and put them in a can and slowly pull them down. I will load new ones using the new load.

Well played

Ahhhh, off topic but, forming a sentence in ENGLISH helps the reader a bit. You know, punctutation, sentences that start with capitol letters, etc. Highlighting our poor educational system is annoying.

No, I'm not a teacher, english major, whatever. I'm an engineer and even I write better than that!

Lowering the pressure of your loads will help
I have experianced the same issue before, it was not my loads being to Hot.
I did some research and found that Federal Match primers are to soft and thin for use in the AR, which uses a floating firing pin, you can actually get a slam fire.
CCI 41, CCI 400, CCI 450 and remington Primers are thicker and harder.
