1in thick 12'x12' of AR500 steel should do it
I seen a shooting show were Jerry Miculek had made a portable bullet trap on wheels. But it would be very expensive to do. One 4'x8' sheet of 3/8 AR400 (bare min.) cost around 1,000.00.Well I have 11 acres actually just south of tophat45s place. I was interested in seeing if someone had built a bullet catcher on wheels or such. Not really a full blown range, just something to shoot 10yrds with.
Thanks again.
I've been using a large round hay bale as a back stop. Ive shot everything from a .22 thru a 30/06, .50 cal muzzleloader, 12 ga shotgun slugs. I have had the same bale up now for 2 years and still no pass thrus. I know because, 1) there are no penetration marks in the wrapping on the back side, and 2) the trees behind it arent damaged
