Obviously reloaded from military casing. Weight is 390 & 396 grains. Nothing magnetic about them.

Some guy’s lead gas checked reload experiment?
Heavy bullet seated waaay out in order to stuff enough powder inside?

I had some of these in my sale bins & neither the person who I got them from or others I asked knew anything bout them.

So I’ll go with Texican’s theroy

Interesting, they look like subsonic loads using swaged bullets with short jackets, not gas checks. I don’t know who made them.

I pulled it down.
Powder is 28 grains of ball.
Bullet is 180 grains.
