I would like to hear ideas on building a better bullet trap.
**Back ground**
I was out to the bowyers today with my youngest. (the boys getting a VERY nice bow (nicer than mine

) for Christmas) My bowyer was going over stance, form, release, follow thru and everything with the kid, letting him shoot different bows and basically getting the info he needs to set up the kids bow so it will be ready to shoot X-mas morning. Telling the boy the whole time he was setting up a couple bows for other kids and that he was his lab rat.

ANYWHO: in our conversations over the past few years we have been doing buisness together, we have come to realize we are both BIG into teaching our youth...hes an accomplished archery coach, i am not to terrible at coaching kids in firearms safety and marksmanship.
Well, hes looking to build a good bullet trap and maybe getting into doing some indoor .22 shooting (with my help



) to go with the indoor archery range/weekend youth shoots.
I have an idea of how to build the trap...
Set a sheet of SOB up to hold targets, behind that a sheet of 1/4 plate hot rolled steel ( high carbon) set on a 30 degree downward angle, deflecting the bullets down into a bed of saw dust.
Any better ideas?
