I have some cases of surplus 8mm.
It is not worth shooting.
It is not accurate, and the primers are corrosive.
The bullets are not worth pulling down and the powder is not worth pulling down.
Winchester or Remington brass with Sierra bullets and IMR4895 or H4350 powder will make good handloads that get good groups and don't wreck the bore.
Save some time and stop trying to save money.
Don't be slow to catch on, like I was.
