Jake KNOWS NOT to touch MY brass !!!!!LOL, That's what 308jake wears to the range. He'll catch your brass before it hits the ground!
That's a problem easily solved.
You held this thing next to your gun as you shoot.
Same thing with a rifle:
I was at the range yesterday and wouldn't you know it, halfway through the time I allowed myself I had to use the restroom. By the time I got back someone had swept up all my brass and took it with them! The nerve of some people! THANKS!
I tried one of those with my revolver and it didn't work worth a darn. Total waste of money.
