I just bought 10 boxes of once fired brass for my 7mm rem mag. My concern is the age of the brass, although I'm not exactly sure of its age, the boxes the brass are in appear to be fairly old. Should I have any concerns?? How can I tell how old this stuff is?? Can send some pics of the boxes to one of you if you think ya might can tell the age of them. Thanks! Brian 432-238-3937

Age has no bearing on the usability of the brass. Brass goes bad from being worked and not being annealed. Just clean them up good and load away.

I have some one fired 1940's 300 Savage brass that I had to throw away because the cases were splitting. Had one of the cases tested at a metallurgy lab and found that the ratio of zinc to copper was considerably different than modern brass cases. It was much more brittle than today's brass. Based on that evidence I would hesitate to use brass over 50 years old. I think, in general, that Dee is right but age is a factor when you are dealing with very old brass. How do you know it is very old. You don't unless you have it tested and compared to new brass. Is it worth taking a chance?

I see now that you are talking about 7mm Rem Mag. Given the age of the caliber I would not hesitate to use the brass. It will not be that old in the grand scheme of things.

I'm thinking its 25-30 years old at the most, figure someone would be able to tell based on the boxes they're in.

7mm Rem Mag was introduced in 1962. Any brass will be just fine. Just clean it up, tumble it and check for problems like split necks, bulged case and case head separation. The things you would do with any used case.

A factor could be in the manufacturer as mine is gi brass.

If its once fired factory and full length resizes easily I'd clean and load it. If the primer pockets seem a loose fit I'd toss it.
