Hang Fast Targets has this T Post hanger Multiple targets can be used on the same T Post.
You must be using one tough camera !
When a lead projectile strikes hard steel the bullet fragments in a 360 degree pattern at about a 20 degree angle away from the plate. Placing the camera slightly behind the target or in front off to the side a little puts the camera out of the splatter cone. THE STEEL MUST BE SMOOTH AND HARD.
This theory is foolproof with cheap cameras ;-)) I've never had any splatter hit the camera though.
