There are some that reload the wolf cases? check out youtube if interested?
If you are fortunate enough to have a metal recycler/scraper in your normal travels, save it until the bucket is full. last year when metal was at its peak. I got about 5 to 10 bucks for 5g bucket. this year....complete junk cars getting 75/100 ton.
Take a light and look down in the case. If you see one hole for the primer, and if the case is brass, you can reload. If you see three holes it is berdan primed and reloading is nigh unto impossible. Take a magnet and see if the case is attracted. If so, it is steel and difficult to reload without doing damage to the dies.
To reload boxer primed steel cases.. First clean and tumble very well.. When they are spotless and you can tumble with a dry white towel and its stays clean..shread some paper towels with a little tri-flo on it.. and tumble for a few minutes so they have a thin layer of tri-flo on them.. Load as usual..Remember to deburr the primer pocket..and remove crimp if you have one. In countries where you can not buy any ammo in a military case size.. You'll quickly learn to reload anything you have.. even the berdan primers..IF you can get the primers. Spotless cases is the key to good die life.. In the past I've loaded countless steel 45 ACP cases without problems.. and a little 8mm Mauser..
Good job on picking up your casings ... I wish more shooters would do that. It seems that when I come upon a shot up dump site (illegal) there are tons of those steel case 7.62x39s and .223s laying around.
