Hey guys. I use a cardboard box and shredded T shirts to catch pellets up to 25 cal but I recently bought a Texan 457 CF and I wanted to build a trap to catch the lead. Wondering if I could scale up to a much bigger box or if I have to get a steel trap. I don't really want to go with steel because of the sound but I will if I have to. Any other suggestions would be welcome as well.
