Non drying Modeling clay.
Rubber mulch.
Use the Priority Mail boxes from USPS.
When shooting wrap box in Duct Tape.
When Duct Tape won’t hold the box any longer, I dump everything into my 5 Gallon shop vac.
I fill with water.
The rubber floats to the top and is reused in new boxes.
The pellets are melted down into and then cast into an ingot...
This makes me want to start a new thread about casting I’m wanting to but have zero Idea what I’m doing.
my indoor trap is a box I built it’s 18in tall and 16 wide. Has 3/4 solid steel plate as a backing and about 8 in deep - I mixed spray foam insulation with rubber mulch for filler then for a face thick cardboard and replace it as needed. With that steel plate pretty sure I could pop my 30/30 win in it and be fine. My r5 super long shooting 61.5 g nsa slugs at 900+ doesn’t even make it twitch

Rubber mulch advocate here too. But....I always see posts like FrankinFairfield’s saying their rubber mulch floats in water which allows them to separate the pellets. I have had no such luck with the mulch purchased from Home Depot or Costco, other than a few small pieces that float with the surface tension of the water, the majority of them just sink. I would be interested in what brand floats.
