Primer Anvil

[JRS]

My NORMA loading book also states "the industry standard is referred to as paper foil". A quick google search lists a number of sites that not only list foil as one of the components, but also have pics of the primers. I'm not quite bold enough to tell NORMA and Sierra that they don't know what they speak of.

Take a few apart and show us the foil.

JRS -

Regardless of the contents under, the anvil's are proud by nature of it, just as MagnumManiac and Matt stated above.

Donovan

The anvil is below the top of the cup. It isn't proud. Even if it were flush with the cup, it wouldn't be proud. The grain in certain types of wood are sometimes referred to as "proud", although the grain is flush, and not raised above the piece of wood.

Sorry but MagunManiac has it right. I saw a video on one of the big ammo makers. I don't remember which one, it was probably 15+ years ago. The primers we get and what goes into the big makers factory ammo are slightly different. Primers supplied to the reloading market are shipped with the anvil not seated all the way for safety. The edges of the anvil ARE slightly proud. When we seat the primer all the way down in the primer pocket the anvil is pushed in and fully seated against the priming compound.

So yes clean those pockets and make sure your primers are seated all the way down for the most consistent ignition.

Below proper seating of a primer with preload.

Military 7.62 ammunition requires the primer to be .008 below flush.

+1.......... agree

I'll keep working on it. RWS has the paper foil, Wolf has the paper foil. I'll try the S&B next, then the American made primers. I suppose it's quite possibly a European thing? After all, they were making primers before the U.S. existed!

 

[CatShooter]

There is a small article explaining the components on the Sierra website. ExteriorBallistics.

What is the URL for that??... I went to look and canot find it.

... USA existed in 1776... first primers 1842.

I missed that by a few years :-\

Found it...

 

[CatShooter]

Can't answer that for you. I honestly don't know, without contacting the different manufacturers. There is a small article explaining the components on the Sierra website. ExteriorBallistics.

I just got off the phone with Duane, at the Sierra Ballistics lab. He (embarrasingly) said that comment was 25 to 30 years old, and they do not stand by it any more.

It is amazing when you can find out by asking people that really know....

Amazing, the things available when typing in the search using the correct wording.

JRS -

My meaning of the word "felt" was not intended as in a felt cloth, which is one meaning of the word.
I was using it to its other meaning; mat, or; mat together, or; matting together.

Also, the anvil to all the primers I have (CCI, Fed, Rem, Win, Wolf) are all proud of the cup, as well as the felt/mat.

Donovan

 

[JRS]

It really doesn't matter how we refer to it Donovan. Nevertheless, it's there. I tried to remove it from a Wolf LM primer with an x-acto knife and tweezers. It is obviously embedded into the compound. I would also imagine it is there to serve the same purpose it was originally designed for. To keep moisture out of the compound.

Ok , now to all the info out there about primers. Are they half full or half empty ?

 

[Hoser]

I found this in a box of Federal Large Rifle match primers a while back...
