I dropped into my local Wholesale Sports Outdoor Outfitters today just to have a look around and walked out with a Champion .22 Caliber Bullet Trap. I figured the time had come to stop using cardboard boxes as my backstops, sure I have lots of backyard and so safety is not an issue but I think this new Champion Bullet Trap will work well for me!
One really nice feature about the Champion Bullet Trap is that it's rated to shoot right up to .22 caliber rimfire bullets (no magnums), so I can use my Henry .22 rimfire Lever action rifle with it too.
I am hoping that it will trap BB's OK, if they tend to get a little lively in it I may have to through a little cardboard in behind my target paper.
The only trouble I encountered was getting it home as I brought my Kawasaki KLX250SF motorcycle with me on this trip but fortunately I had installed a rack on the back that the Champion Bullet Trap fit nicely on to.
