Ok, need some help

[Howard Shadix]

Well I’ve come across something I’ve never seen before. I had some Federal Premium 7mm magnum cases that have been sitting since 1991. While cleaning I decided to go ahead and clean and de-prime, who knows I might get another one after all this time. After tumbling,as I was set to de-prime I noted a piece of paper in one. Cleared and continued. Then I noticed it in several more cases so I fished it out with a paper clip and took pics. It’s got the consistency of a light paper like product and fibrous like old news print but thicker. It wasn’t in all of them and it wasn’t intact in the media if it came out of the others. Brass was kept in box in a military ammo can since 1991.

What is it???? Very curious, a filler to make case “full”?

I am guessing some type of filler. In for the answer.

Someone was worried about moisture maybe

 

[Howard Shadix]

I might message Ron Spomer. He’d probably know or even Federal themselves.

If they were once fired shouldn't be anything in there. If you weren't the one that shot them it looks like the work of a bored 5 year old. Usually you'll find dirt, stuck tumbling media, bugs, spider webs etc. I'm thinking bored kid.

I hope it is not asbestos brother.

Throw it away asbestos doesn't burn.

 

[Howard Shadix]

Already threw it away, I actually have almost 2 boxes of the same ammo from 1991, I thought about pulling one down to look inside.

Just found this:

Fillers for Reduced Rifle Loads - Shooting Times

Two classes of fillers for reduced rifle reloads are 'puffballs' and granular. Puffballs are the most troublesome, but granular is no cure-all.

www.shootingtimes.com

Doesn’t answer but still shows it’s been a thing at some point

 

[Howard Shadix]

Also mention of Kapok in a few places but always in the context of reduced loads.

These are factory load Federal Premium 7mm Mag, maybe they were larger scale testing a powder or something.
