Somewhere I remember seeing material that could be bought for the back of a shooting range to absorb the bullet. Looking to stop 22's in a home range. Please let me know who has this stuff for sale lost my info. Thanks Ron
First line of defence is a GOOD trap.
I used the Outers .22 trap. Worked great for me.
Second line of defence is IF/WHEN you miss the trap.
A concrete wall is a good idea.
Or 1/4" plate at an angle (maybe 45 dergees) to defect the bullet into a sand pit.
I have a moving target set up and would like to back it up with a trap maybe I could use 2 or 3 outers traps behind it as its 3 feet long. With the concrete wall behind that. See pic of moving target. Feedback wanted! Thanks Ron
Conveyer belts work great. Factories and quarrys usually pay to get rid of them. One layer will stop a 22. Two will stop a 45 (depending of course on fow thick they are).
