Thought I'd share my personal back yard bullet stop here also. I have plenty
of rubber if needed to replace those shot up from being concentrated in the middle. Most of the rubber slabs are from a cousin who works at a re-thread
tire company. All those throw aways are slabs of rubber before the steel re-inforcement is put in. It stops a 25-06 and .222 plus the smaller .22's very good. Has also stopped a .357 Mag and Max in cast boolits also. Am thinking
about putting in a sand trap between the 1st 3 slabs and the last 3 inside the steel plated box. Has 5/8 's steel for back stop . Boolits fall into the trap
below . Just want to recover my casted lead for re-use later.
