Plans for a home made bullet trap?

[Brett]

I'ld like to make a bullet trap for plinking with the .22 rifles and small caliber hand guns.   I have access to boiler plate and welding equipment but need a good set of plans for a trap.  I've searched high and low on the Internet but haven't really found what I'm looking for.   Any body out there ever build a trap or know of where I could get a good set of plans?

Most bullet traps I have seen are nothing more than a metal box with the back plate set at a 45 deg angle to deflect the bullet downward into a catch basin area.  They are not hard to build, and depending on how heavy metal you use as to what caliber you can shoot into it.

This is another design I like, harder to make but also pretty good.

  Brett,
     I had a fellow help me build one when I was a kid. We took a 55 gal. drum and cut a square hole in the side about 1/2 way up. We made the hole large enough so a piece of plate about 14"X14" would fit in it. He did the welding for me and welded the plate at about a 45° angle and put some braces on the bottom. Mine would stop anything up to a .22 mag. I shot it twice with a .38 but it put dents in the plate so I stopped. Filling the bottom with sand will also keep the rounds in the bottom once they hit.
  One word of advice, if used inside they are loud no mater what.

Brett, I'm not sure if this is what your looking for but here's a link. Take a look. Pretty simple if you ask me. You might want to add some sort of handles, maybe add a bottom that would hold sand. Depends on how portable you want it.
