Sorry if I'm beating a dead horse but....
Intenseaty brought this up a bit ago and I was working on this, just a bit slow to finish it. So I had this weird pull cart free from work and some mildewing treated lumber laying about, and my 20th version of a rubber mulch filled box was worn out so...
Build a treated plywood box and attach to cart,
Line back with 4 layers thick of 18 ga. sheet steel. (sorry Yo, no 1/4 " plate)
Test with .25 H&N hornet from Taipan.... um.....
Puts a heck of a ding in those Plywood backed layers but... OK!
Put a ledge around the inside to lay cardboard on (I chose 5/8 thick for 4-5 layers of cardboard which hold the rubber mulch in) and add a hinged frame to pinch the cardboard tight,
Fill, add target and enjoy! it's a heavy thing, thus the wheels. I roll it into a shed when done shooting
It was a slap together/low cost project but I assume I'll have it for years to come.
