I recently completed a move. I live in a rural area and was burning some trash rather than move it. I remembered after the fire started that I had a few rounds of 8mm Mauser in one box.
Didn’t even bother me. I just got around 20 feet away a listened to it explode. No real danger unless you are very close. I have actually been hit by the casing of a .22 which came from exactly the same thing, accidentally burning. It stung just a bit but did no harm. Probably wouldn’t want to get hit in the eye tho.
'Round these parts, you'd need permits from seven different agencies for that to occur ........God-Bless the rural life!
