This report tells you how to make a great pellet and BB trap for under $10. We have seen this before, but there are lots of new readers who may not do the research in the Search box, so let’s dive in!

Guest blog

This trap was first shown in a guest blog in April of 2015. Reader Rod took us through all the things he had done to make a successful pellet trap and ended up with what I am going to show you today. Not only did it stop pellets from powerful airguns, it also stopped ten .22 long rifle bullets and five 55-grain bullets from a .223 Remington (the civilian version of the 5.56mm military round). The range master forced him to place the box out at 50 yards, but Rod was sure the box would stop the long rifle bullets even closer.

We don’t want to make a bullet trap. A pellet trap is our goal, and this one stops pellets and 40-grain bullets from the long rifle in about three inches, when it’s 50 yards away. Pellets stop in three inches from 30 yards.

It’s a 12x12x10-inch box. You can buy them for 86 cents, or you can just recycle one you find around the house.

Rubber mulch

Fill the box with rubber mulch that can be bought at your local home center. One bag fills this box exactly. A 0.8 cubic-foot bag (a common size) costs $5.00 to $7.00. Except for tape to seal the flaps of the box — that’s it!

Rubber mulch is made of tires that have been ground up into small pieces. Sometimes they are colored and sometimes not. But those particles are very tough and they stop pellets, BBs and even bullets fast.

Reader Rod recommended putting a terrycloth towel on the back seam of the box so nothing would get through the taped seam. That towel stopped one 55-grain bullet from a .223 from exiting the box when it was shot. The other four didn’t make it even that far.

How many rounds?

As good as it is, eventually the box will be so shot up that it has to be replaced. According to Rod, that’s after thousands of rounds have been stopped by it. Changing boxes is a one-minute drill with no added expense.

It works for BBs, too

One of the best features of this trap is it also works for BBs. In fact, that is my primary use for it. Remember a couple months ago when I was training the Royal Rangers gun safety and how to shoot? Well, I made two of these traps and as long as the kids hit them, the BBs stayed inside. At 5 meters I would have said the boxes couldn’t be missed, but that was a lesson in “Never say never.”

I reckon each box will stop tens of thousands of BBs over the next 10-15 years. I probably won’t be around when the boxes need to be changed.

Line the box?

Is it advisable to line the box with a large plastic bag? I don’t know. Rod didn’t do it and I made two of these and didn’t line either one. I think lining is an extra step that isn’t necessary, but if you want to, by all means do so.


Another benefit of this trap is it is totally quiet. The only noise it makes is when the cardboard is penetrated. And the noise of the discharge masks that. So in essence, this trap is silent.

This one is best

Over the years I have had several BB traps. One that Daisy sold was made of white foam and had a steel plate inside. Plastic wrap kept the foam inside.

Daisy’s target cube was white foam with a steel; plate inside. It was wrapped in plastic to keep the foam from crumbling.

The best one was imported from China by Crosman. They called it their model 850. It had ballistic cloth screens that slowed the BBs as they entered the trap, and a thin steel plate angled in the back stopped them. Most BBs then rebounded off the steel to hit the same curtains as they tried to exit the trap. If the front of the trap was elevated a little, about 95 percent of BBs were stopped by this trap. The rest bounced out the front and went on the floor. But this trap was light and it worked well most of the time.

The Crosman model 850 BB trap worked well enough.

UTG copied the Crosman BB trap, and when Crosman stopped selling it years ago, UTG was the only game in town. But there apparently isn’t much money in BB traps, because UTG finally ran the curtain down (pun intended) a few years ago. Why?


BB traps don’t sell because people don’t think there is a need. And maybe for a dad who wants to shoot BB guns with his kids one time, there isn’t. For him the old standby of a box full of crumpled up newspaper works fine. Maybe they will shoot 150 BBs into that trap before they move on to building a Hot Wheels racetrack.

But for people who shoot hundreds and even thousands of BBs, a good trap is a must. I have worn out the curtains in my UTG trap twice already and the tests keep coming.

Today’s idea is so good that I made one of these traps for myself for use at home. It’s heavy, but it stops anything I shoot at it — pellets or BBs. Nothing bounces out to get on the floor and that is something I can’t even say about my steel bullet traps when I use them for pellets. Even they allow a little lead to splash out. But not this one.

Why Part 1?

This trap is simple enough to make. Why is this a Part 1? Well, a Part 2 is coming. What will it be?

Part 2 will be a penetration test of this trap. I think I will shoot it with powerful airguns and also with .22 long rifle cartridges — from just a few feet away! That will be a real test of the stopping power of this trap.


Today you have read about a pellet and BB trap you can make for very little money, and it’s one that surpasses most of the others. If you shoot, this one could be for you.
