Misfiring primers.

[Zermoid]

Cat Shooter:

Believe it or not I have has the least trouble out of Winchester primers. I have loaded comercially millionws of them. The most accurate have been Federals .205m, 210m, and 215m.

Russian Primers are not consistent in their depth.

CCIs have been accurate but you can count on about 1 or 2 out of 5000 not going off.

Since I began keeping my primers in a warming,dehumidifing) bread box I have little to no misfires.

Hey, Just a thought on the matter, I know CCI,and I assume other makers) use water as part of the process of making primers,was told this years ago by CCI tech guy, I had alot of primers get wet after a tornado riped the roof off of our house and wanted to know if this would kill them) and was told that as long as they are thoroughly dry before use they should be fine. I'm wondering if CCI packs and ships their primers before they are completely dried out? Would explain why the guy who "bakes" his has better luck with them.

I never use BR primers just the regular ones but have had no real problems with them, even buying CCI primers at Wal-Mart!

 

[CatShooter]

I donno, but I have lost faith in them and will switch to something else when they are gone.

I also got a bunch of e-mails from guy that had the same experience - so whatever is wrong, it's not just me.

Try to use bench rest primers have had a mis fire yet

Catshooter,
It is my understnding,could be wrong) that .060 is proper firing pin protusion. I use a titanium firing pin, steel tipped with a Wolf spring and have never had a click bang. If you are looking for accuracy there is nothing that will compare to the Russian primer. Standard deviation of 4 and 5 fps is possible. For the long range shooting 600 to 1000 yards primer selection is critical. Under 500 I doubt it makes much difference.

I bought a brick off normal CCI LR. I loaded for my 270Win, and had 3 hangfires in 20 Rounds...after that, I had a few more. I was told all kinds of things, like my cases were wet, I must have washed them with thinner etc etc..I started doubting my own loading skills!!
Cheers

Ok, I know that I am a nobody, my <10th post. I too had problems with a 7 Mag and 220 Swift using CCI Mag primers. I was experiencing FTF, but never a hang fire. Being a 7 Mag, I wasn't shooting it a lot, so the few that I had were a lot in my book. The 220 was being shot a lot and out of 50 I would get 5-8 or so. Both had very healthy dents in the primer cup. Some would fire after a recock, some wouldn't.

I checked my firing pin protrusion for both guns and it was .058" on the 7 Mag and .053" on the 220. After reading that Savages should be in the .040" range, I readjusted and I have yet to have any problems. Around 50 rounds down range on the 7 and over 300 on the 220 Swift.

FWIW.

CatShooter - Not all primers are made the same, but you know that. The only problem I ever had was with Wolf ammo in my mini-30. I bought it used and it would only fire every third round. Took it back to where I bought the gun and they put commerical,winchester) rounds in the gun and it fired without any problems. Even though the Wolf ammo was dimpled by the firing pin it would not go off,scarry). I only use Winchester primers,they are softer metal) and have had no problems. Their accuracy in my loads are right on. I know a lot of people are hung up on primers for accuracy, but it is not so except in real cold weather conditions.

I would bet a buck,$1.00 US) that if you replace your firing pin,yes they do wear) all your misfires will disapear. Since you are having problems with more than one brand of primers, I would look to the rifle. Your pin mightbe just starting to fail.

It can't hurt and does not cost that much for a new firing pin.

Good Luck

I stopped using CCI primers many years ago, because of misfires and hang fires. I had problems with both BR-4s and BR-2s, and actually threw out a bunch in the trash.

Since then, I have used 9-1/2s and Wins.

I recently started using the BR primers again cuz my local dealer stocks them and Wins were in short supply. I bought a few brick of BR-2 benchrest primers.

A few weeks ago, I loaded up 50 rounds of 264 Winchester Magnum,new Winchester cases) and H-4350 powder.

First 50 rounds I got three short hang fire "Clickbang", and one long hangfire... "Click - - - - - - - Bang" :,

Now, H-4350 is not a hard powder to light!!

Yesterday, I was shooting the first batch of 6mm Remington loads. Also, new cases and H-4350.

The first 5 rounds gave me one complete misfire - the primer is very heavily dented.

Both powder and primers are fresh and kept dry, and I had no problems when using the Win primers up until now.

In both rifles, the firing pin springs are fresh and stronger than factory springs - they are 28 pound Wolff springs.

I am NOT a happy camper since I now have a bunch of these!!

Anyone having similar problems, or am I not pulling the trigger hard enough. :,

Catshooter, I've been having the same problem with my BR-2 primers. I too have about 5 out of 100 shots misfire. This is with both virgin and fireformed brass.

The federals work fine.

Catshooter is no longer a member of this forum and this thread is 8 years old. Interesting that the problem seems to still exist. dedogs

Well... CCI finely called back.

They have lost a customer,except for the BMG primers).

He says that the primers are not seated deep enough - I use an RCBS bench priming machine,the old Lachmiller machine) - and I seat them hard...

He says that if the primer doesn't fire, then it should have a very light "strike"... Well,Duh) if the case has a working headspace of 0.002" and the pin protrusion is ~55 thou, then the primer dent is 53 thou - that's half of a tenth of an inch! That's DEEP!

OK, Dm... I know - I need to chill - naw... I need a drink, and I really need some Win primers.

Where do they find these phone guys, the homeless shelters?

Had the same problem with BR4's. Contacted CCI & got the same answer as you did. It's called passing the buck.

 

[sfldiver]

I exclusively use BR2's, I can only think of 1 misfire I've had in the last 2000 rounds.

 

[dkhunt14]

The BR series of primers have the thickest cups. Most of the trouble with misfires is because of too light of hit or not seated hard enough. Actions with weak or light poundage firing springs seem to have this problem. Lightweight firing pins or too short of pin fall is another cause. Most times it is not the primers fault. They were made tougher to handle pressures from cases like Dasher so they dont blank. Matt

I too was having misfires in my rem 700. I checked everything and me and my gunsmith couldn't find anything that was the problem. this was in a 25-06 that is my pet. I finally took a shell that I tried to fire 3 times and got the bolt out of my rem 7mm mag and tried the shell again and bang off it goes! I sent my bolt off to greg tannel to have a new fluted firing pin and have the firing pin hole brushed and man what different. this man does great work. tried all my misfires and all went bang!

Matt hit it right on the head!
usually a combo of firing pin length, spring tension or primer seating depth.
