Are Rem. primers softer than others? I had a round go off in the mag. box on my Brno 602 -.458 it seems that there was a high spot on the mag. box that hit the primer during recoil. I have found the same marks on other primers Fed. , Win. Wow

Nope. That high spot in the mag is why your rifle is damaged. Mind you, the primer may not have been seated deeply enough.
 
Ya I am fine, surpirsed as all get out but ok.I was sure that that was the cause,but there are the same marks on other ammo with out a problem ( yet ).The mag. box held together and other than the stock witch I think is toast and maybe the mag. box I think everthing else is ok.I will ship it out to my smith for his opinion though. Boomer is going to post pics.

I'll try to get the picks done later today and post them tonight. This does bring up an interesting question - what actually happens in a mag box when a round is fired in the rifle? I always thought the rounds in the box moved forward, which can be proven by the flattening of lead point bullets, and by bullets being driven back into the cases when there is insufficient crimp applied in powerful cartridges.

Spring tension against the follower should prevent the round from bouncing from the front to rear in the box. If I put a round at the rear of the box in my rifle and fire over it, the round is at the front of the box when I open the bolt. But something caused the primer to fire that round, and as Pounder says there are similar marks on other rounds that he has fired over. I'll concede that the imperfection in the back of the box is the culprit, I just don't understand why it is the culprit.
 
"...why it is the culprit..." Likely where the burr or whatever is. Sounds like it's in just the right place to strike a primer under the heavy recoil. The ammo in a mag moves with the recoil. Just like your head or anything else does in your vehicle when you step on the gas. It's physics. An object at rest stays there until force is applied. Recoil is a force that is applied towards the aft end of the rifle.
The follower just keeps the cartridge up. It doesn't do anything to keep the cartridges from moving forward or back. Non-crimped bullets can do the same thing in heavy recoiling calibres. The right OAL can reduce the movement, but the cartridges will still move.
 
Years back I had purchased a couple thousand Remington small rifle primers for 222 reloading. Some upon firing would develop minute pinholes in the brass primer cup material. Scared the he!! out of me before I realized what was up. Hot gasses kept hitting my cheek while on a gopher shoot... felt like a "pinch" to the cheek.

Checked the bolt face of my Sako 222 Vixen heavy barrel and found it all pitted from reapeated blasts of hot gas. Was some pissed off. Contacted Remington quality contol people in Loanoake Arkansas. Gave them the lot #'s and the reply from the Remington person was simply "oh those".

Remington arms replaced my Sako short action bolt and picked up all the local gunsmithing fees. True story.

How long ago was this, I have been using Remington primers almost exclusively in my Ruger 223 for the last 15 years and have never had a problem with them.
 
I am surprised that thre could be enough velocity on a round bouncing in a mag to fire a primer. But can't argue with the facts.

I don'tknow if rem are soft, but federal sure are. I had one go off in my Lee Autoprime. It blew the machine to bits and put a small piece of it through my shirt into my belly.

Of course, the Lee instructions say that I should not use Federal primers in itbecasue they might explode. It warns that all 100 might go off. Now that would really hurt.

April of 1996. They bolt was ordered from Stoeger in the US as it was ordered by them from Sako in Finland. Headspacing was done in Winnipeg by Prairie Defence Technologies, formerly Prairie Gunworks. Rifle was fully operable through the whole thing as the pitting on the bolt face was mostly cosmetic.

Have to say Remington was more than cooperative through the whole affair...and yes I still do use remmy primers, large and small rifle.
