I just bought 22 rim fire bullet trap and it works like a champ inside. Great for practicing my off hand shooting. I tried today and it didn't move 1mm when the projectile hit the back stop. Has anybody tried a 22 mag. in the one Champion makes? This going to have buying 22LR ammo more often but I have a good source for it so that's no big deal. I would like to practice with my 22mag. but I am a bit reserved until I have an actual real life account of it being done.
