Not sure if Im posting in right spot:

Heres some swinging targets Ive made from scrap I pic up here and there. Working at an automotive dealership has its advantages.

(far left) 6"x8"....center is 1"x3".....right is 5"x3"
My favorite is the center. Its made from shackle U bolts from rear diff.,,,heads bolts from a diesel, and a piston rispin from a 6.4 Ford diesel. Ill put those from 1 out to 300. Believe it or not, I can smack the holy crap out of that rispin (308)and it does absoltely nothing to it.
