cartridge OK to use?

[jeb111]

Not worth chancing damage to you or your Luger. I wouldn't shoot reloads from an unknown source. I think you should pass.

1. NEVER shoot someone else's reloads through your gun.
2. NEVER shoot your reloads through someone else's gun.

It doesn't matter if "he's been reloading for years".
I work on guns pretty regularly that are damaged from " My buddy gave me some of his reloads to shoot, and now my gun doesn't work".

You have NO IDEA how much of what kind of powder is in those cartridges, unless you loaded them yourself.
Unknown handloads are a recipe for disaster.

The only safe road for that ammo is to pull it down and start over. If you have the time and want to make the effort.
