Making your own SILENT pellet/BB trap

1067 19
40 years ago I lived in a big ****ty and belonged to a pistol club to shoot anything I'd travel several miles in gruesome traffic, so I decided to shoot at home in the garage got me a couple airguns a rifle and I already had the pistol. i tried the cardboard box with carpet strips but it was not ideal.
I decided to build a genuine silent pellet trap. I built a box out of pine 12x12 x 10 inches deep the back of the box
is open and I placed a thick piece of plywood that was held with 4 screws so That I could get in the box to empty it
The front is also open to accommodate a regular clipboard. I carefully cut the clipboard to make an opening all the way round to be able to use card stock for targets, the clip holds the targets
for targets,. Went to a local electrical supply store and bought 12 pounds of Duct Seal,
( it's the putty that electricians use to seal big openings when they run conduit) At home I stuffed the DS into the box
to make about 4 inches thick it covered the entire inside of the box. I framed the front of the box with 1x4s to contain any pellets or BBs that bounced of the seal and drop in the bottom of the box, after gazillion pellets a few bounce on the ones in the seal. i have built several over the years always improving latest has a channel to insert the clipboard.

Fill up the Priority Mail boxes (free at Post office) with plastic trash bags.
The plastic will stop the BBs.
When the box gets shot up, empty out BBs (shoot them again) and get another box.
You can also use rubber mulch.
Rubber mulch is good for pellets.
Me, I use duct seal (it looks like C4) (get it in the electrical department at Home Depot/Lowe’s.
Stops the most powerful pellets if you pack it three inches thick.

Great idea. How far do you think the pellets penetrate the Duct Seal?
First ones about an inch as they load up it's less.If you pack 4 inch thick it will stop the magnum rifles at about 33 feet
from the target, do not try any rimfires unless you have a good 1/8 inch hardened steel backing plate.

I have seen and though about dust seal. But assuming I have tight groups I would guess the hotspot would soon be overwhelmed. What is your experience?.
Nope they just hit the pellet that's already in there and deform. I've shot thousands of rounds in the box.

Just move your target off to one side then the other i'll try to get you a better pic of the inside of the box see the pellets in there.

I used an old rickety fruit crate. Removed the old nails, then pre drilled the same holes for screws. Used wood glue when I assembled with screws. Drilled the backside and edges/corners for a little zip tie reinforcement.

Filled it with three slabs of that clay stuff sold by online airgun dealers for renewing one of their pellet traps.

I use some clamps to act as a bracket for holding an inexpensive clamp-on reading lamp. Targets stay put with nails pushed through the paper and into the clay.

When pellets stack up after months of shooting, dig some out and shoot some more (it is used a whole lot more than this old picture shows)

Will work for the rest of my lifetime

sorry about the order of the photos- they’re best viewed from bottom to top.

Whatever works I also clean up the pellets when I get too many and melt the into bullets.

I make shooting boxes out of wood for the yard.
Some folks use electrical boxes like the ones on the side of your house and mount them on a movable frame.
I use a smaller 6” X 12” X 4” electrical box for my garage targets.
Filled with duct seal.

I like that pellet trap idea going to make one, thanks. My sight in target board is a 1/16"x12"x14" steel plate with a high density foam pad then covered with conveyor belting. It hangs from a tree and has an angled lower tray to catch deformed pellets when they fall. My main target stand is to the right of it just lets pellets drop onto a plywood base or off into oblivion.

It may have been obvious from what SOUTHERN S/PAW said earlier but let me point out that pellets and pellet clumps can be easily removed from duct seal with needle nosed pliers. Since pellets stack and stick to each other when fired into the trap, the clumps that form at/around the bullseye position aren't really a problem but you pull out pretty much the whole clump in a single motion when it comes time to clean the trap. The duct seal can be smooshed around and evened up to get back close to the original layer or another layer can be added on top of what is already there. As was also mentioned, the removed pellets can be melted down and made into fishing weights, lead soldiers or whatever you have molds to make.

Duct seal isn't that great to use as a BB trap. The BBs stuck into the duct seal serve as hard surfaces from which subsequent BB can ricochet. It is better to use something like the box full of plastic bags or rubber mulch.

Right O. that's why I have a strong magnate attached to a stick to pick up the errant BBs.
