I am looking to build one and the only thing holding me back is the expected life of the duct seal. How many shots can it take before the seal need be replaced ? Dumping that big mass of seal seems to be quite unfriendly to the environment.

Duct seal is nice, but it's heavy and expensive. 
A cardboard box filled with rubber mulch works just as well and is much lighter.

I have been using the same duct seal for over 10 years.  Picking out the pellets with tweezers is easy during a baseball or football game.  Eventually, you will need to add a cake or two of duct seal to some areas.  If you use paper targets with lots of targets per page you will spread the impacts over the entire target instead of just the center.

I totally agree with David, but my trap is about 20 years old.  My trap is more than large enough to handle  full 8 1/2 x 11 sheets, and I shoot all different types of multi-bull targets to spread the hits out. I rarely clean out the pellets, and have never dumped out the whole thing.

Another Duct Seal trap user.  I have used mine for years.  Get a little splatter of seal or pellets from the trap on occasion.  Minimal noise and mine is in use over 10 years without changing the seal.  I occasionally dump the pellets at the bottom of the trap and either add a little to the thinned areas or mash the putty to fill in shallow spots.  Great stuff!  Much less bulky than rubber mulch,  I keep a trap in my wife's piano room and it fits neatly in a china cabinet on its side - looks like  silverware holder.

I'm a rubber mulch box user. After reading all the positive remarks on duct seal I stopped at Home Depot and bought a case.  I'll give it a try.

My opinion is that Duct Seal traps are better for indoor use (if regularly cleaned out) because they reduce the amount of lead dust expelled.  They are also very quiet.  Their weight is not a disadvantage in the house .

I think rubber mulch traps are probably lower maintenance, weather resistant, and lighter to move around outside.

I bought the putty. My problem is now holding the target paper. With my mulch box the mulch is filled to the top and when I close the lid it holds the cardboard and target paper in place.  More first world problems. 😏

I was at a University reclamation center and found the perfect box to use as a duct seal target box. The way it's hinged and shallow depth it wouldn't make a good mulch box at all.

Cut an opening in the lid a little smaller than a standard piece of paper, painted it and filled it with duct sealer.

602a

Home Depot only had 1ld blocks of duct seal so I bought a case of 9.

602c

Normally I would have the target and cardboard backing under the lid and the mulch would hold it in place. I guess I could use like a cotton batting on top of the duct seal for pressure. For now I'll put it on the outside and use magnets to hold it in place. I think magnets on the inside would not hold well enough to take pellet hits. Ta da....

I know this is a thread about duct seal but there is something in everyone home and they are called old towels

oh high powered rifles might shoot through them but for pistols and medium power they are easy to make a great pellet catcher

I put a piece of 1/4 durable foam in front of them and the pellet just collect behind it

just an idea, the pellets shake out real fast and hell the towels are just rags anyway

Well sorry, for me the duct seal thing is not as nice as rubber mulch. Maybe because I was using a 10 meter pistol with not much power but I could hear pellets dropping in the box. Maybe also because I was shooting a 10 meter pistol target so the lead was hitting in a similar area. Personally I'm going back to mulch. Just thought I'd give it a try.

You could always just line the bottom of your box with cardboard or rags to kill the noise. Most folks, I believe, make them out of wood and not metal so the dropping noise is less significant. You can also use a clipboard and cut the middle out and use that to hold and 8x11 target sheet. I think they have ones with magnets that should work for your metal box.

I am wondering if there are different types of duct seal.  The type I got from local stores seems to be on the soft side.  .177 JSB Exact shot from my Pro-sport ( around 16 Joules ) can penetrate More than 2 inches but an article I have come across on the internet said that it should be about just one inch . At a distance of 10 meters, my multi-pump Alecto pistol ( around 7 Joules ) shooting .177 JSB Exaxt RS can do about 1.2 inch. In all cases, the pellets taken out from the seal are not deformed which is another indication of how soft the seal material is. Wondering how thick the seal need to be to stop the pellet from a 100 + Joule Huben K1

That's not duct seal. Sounds more like plumbers putty. Duct seal comes in blocks like those pictured above, and is stocked with the electrical supplies. Yours probably came in a bucket.

The stuff does come in rectangular blocks and from the description provided by the seller, I think it is duct seal

 

 

 

Penetration by .177 JSB Exact RS shot from Alecto multi-pump pistol ( around 7 joules or 5 fpe ) :

 

The pellet on the left is dug out from the seal. That on the right is before shooting. There is hardly any deformation . The swelling of the skirt is caused by the pressure pulse of firing, not by decceleration when penetrating the seal material.

As I said, that's not Duct Seal. I did look up the Chinese translation, and is says "sealant clay", but it doesn't say sealant for what. I looks like it acts more like modeling clay (aka Plastilina, Plasticine), so all is not lost. You can use it for testing hollow point expansion. As a target backing material, it's totally worthless.

This is Duct Seal:

Use a Texan SS on that trap. See what happens

Saw this thread a few weeks ago, that got me to thinking about my own duct seal pellet trap.

I put one together over 20 years ago, using a heavy duty cooking pan that my mother had given me, that measures 10.5 inches wide, 15 inches long (includes the end "handles"), and 3 inches deep.

These days, I think I prefer just using the right size cardboard box, packed with rags... paper is too messy, but the rags work well, and you can easily pack in a new piece of rag if you need to.

But my duct seal trap has seen a lot of use over the years.

I forget exactly how many one pound bricks of electrician's duct seal that I put in it, but has to be about 20 of them, after weighing it.

The "handle" grips on each end of the pan are about 1 1/4 inches wide, that make setting the pan easy for use as a pellet trap... I mounted a piece of 2 x 6 board to use as a shelf on my basement access door that leads outside, and cut a groove in the board to fit the grip on the pan.

The duct seal kind of settles down to the bottom end after the pellet trap has been in place for a long time, so I will remove it from the shelf, pack the duct seal to fill the void, reverse it, and put it back in place.

I removed it a couple of weeks ago, and noted how heavy it was, and that there had to be a LOT of pellets stuck in it.

I didn't really feel like removing all the duct seal, and replacing it, so I decided to try picking out the pellets.

David Enoch posted that he would pick out pellets from his while watching TV, so I figured I would give it a try.

Tried a pair of tweezers that I had laying around, which worked, but found a better pair at a local Michael's craft store.. they were longer, and could bend and adjust the tips to get a better grip... the tweezers came in a set of four, each having a different design for different uses.

I also had a screw driver where the handle had broken off that I found on the road while doing my daily walk, and kept it in a can of various tools that I use when working and restoring old kerosene lanterns.

I added a handle using a wine cork to the end to make it more comfortable... also added a wine cord handle to the screw driver blade.

The screw driver (flat head end) really helps to dig out and uncover pellets to grab with the tweezers.

I wish I would have weighted the pellet trap before I started removing the pellets... after removing and tossing a bunch of pellets, I decided to keep them until I was finished, just to see how many I had in there.

I actually sort of enjoyed picking them out while watching TV, especially during the commercials !

It helps to come up with a pattern to dig out the pellets since the pellets are scattered all through the duct seal... I started at one end, and worked my way up, an inch or two at a time, all the way to the other end.

Once I got done, I used the claw end of a small hammer to fill any voids, gaps, and holes in the duct seal... then placed a piece of plastic (slit open an empty loaf of bread bag) over the  duct seal, and pounded it all flat with a big rubber mallet.

I weighed the pellets--about 4 pounds of them... weighed the pellet trap with the remaining duct seal (pellets removed) and it weighed 21 pounds.

I probably tossed about 2 pounds of pellets before I decided to keep track of them.

I found after years of using a duct seal-lined pellet trap that I don't need nearly as thick a layer of duct seal as I'd been using.  I removed about 3/4 of what I'd had in the past and it works fine to stop pellets.  It's much easier to clean up the pellets afterwards.

Yeah, I agree... although I did find a lot of pellets up against the metal pan... probably when I was firing my higher power airguns.

And lots of pellets that were splattered by other pellets... I suspect from other pellets hitting them.

But I usually over think, over engineer, and often over describe things sometimes... because it's often fun !

A shallower depth of putty to dig through while picking out pellets would make the process a lot quicker !

Sounds like a tongue-twister... How many pellets could plinking Peter Piper pick thru pretty thick-packed pellet putty  that Peter Piper plinked !

a cardboard box full of dirt or sand will work just as well...easy disposal of deteriorating cardboard and easy to pick pellets from... 😉

Makes a lot of sense... really does... gonna try it... I usually have to get my shop vac out for indoor cleanups any ways...

Heck, I've been shooting a Crosman 3500 BB gun rifle that I just bought, into a box of rags... and the BB's are totally reusable from what I can see... if only I could reuse my "lead" pellets !
