When I was shooting last week there was a old shot up caddy and one of the things I found was a balancer so I set it up and loaded a 12 gauge slug in and it destroyed half of the balancer which was about 1/2" think I know it is a cast piece but damn these slugs are impressive! by the way I was using cheap S&B slugs which don't seem to have as much power, as some of the other slugs I have shot.

Yeah, I love shooting slugs with my shotgun. Those things will really leave a hole! WOW!

I'm totally clueless here.
Please define:
~ "caddy"
~ "balancer"

BTW, what distance did you shoot from?

Thank you.

~caddy---Cadillac (GM luxury vehicle)
~balancer----crankshaft harmonic balancer (vibration dampener)

I was pretty damn close about 15 feet can't hit anything that small from too far away with a short barrelled mossberg and S&B slugs.
