I’ve seen all flavors of pellet traps and most require too much work if you ask me.
Why couldn’t u shoot at something like this in say 18″x Â½” ductile iron?–>
The geometry is good and around here I bet I could find something
close for free/next to nothing scrap. It would be free standing if it had the flanges
and I think noise would be minimal. A chunk like that would prolly weigh ≈250lbs.
Even just a thick metal plate set at an angle would do the trick. Cold Roll scrap around here goes for .59 a pound. You could get a huge plate for cheap. it would get all rusty if you didnt paint it though.
