Back stop for indoor range

[jaguarxk120]

How thick should the "duct-seal" be to stop pellets and BB's?
I have two five pound bricks would like to know the thickness
to stop most pellets.

I use a USPS Large Flat Rate box stuffed with newspapers. Throw away and replace with another one or just the newspapers when needed. Work just fine.

It depends on a lot of things, but a couple of inches is pretty good. If you need to go thicker, you can add more assuming that the duct seal is in some kind of a box with a solid back. Shoot a shot, peel it up and see if it went through the ductseal. Shoot a few more in the same spot and check again. If it looks questionable, add some more. It's really dense though.

I do not shoot BBs at ductseal. The BBs will stick in the ductseal and if another BB hits one that is stuck in the ductseal, you will get a ricochet. Shoot lead pellets ONLY. They are soft, and if another pellet hits on a pellet already embedded in the ductseal, they just sort of mash together and there's no bounceback.

If you want to shoot BBs, you need a different type of trap.

I use electrical junction boxes so I have a steel back as a failsafe. Honestly I like about two “bricks” worth of depth. My first I made with a ton of duckseal and it will will stop ANYTHING.

If you are shooting higher powered PCPs you might want to go thicker just for piece of mind but duct seal really sheds the energy fast.

I don’t know if this helps but I shoot up to about 900fps .177 or 750ish .22. Those are my powerful airguns.

Yes I know this one could use a cleaning.

Flat-rate postal box really works well. Very few rebounds to have to sort out, too.

Thanks guy's that's what I wanted to know.
I have two "bricks" of ductseal that should do nicely.

For what it’s worth my trap uses like 7-8. Bricks iirc. It’s been a while.

I have the big 5 pound bricks.

My backstop is a cardboard box that holds 5-6 lids from 5 gallon pails - even at 5-10 yards, no pellet form my RWS (1000+fps) has ever penetrated all of the lids....................

What is ductseal? What form does it come in? Just purchased air rifle .22 cal. 950fps at best. Also air pistol .177cal. Can be pumped up to 10 times. Would like to setup indoor range. Thanks!

It's this stuff.

All of the big DIY stores carry it, but usually you have to find it yourself. It's in the electrical section where they have the electrical duct materials.

It's a non-drying clay with a very thick consistency.

A pressed hay bale makes a perfect indoor target for $17 have used on for years

I just use a GAMO pellet trap. The square funnel type. I only shoot CO2 pistols into it at about 20 feet but it contains the pellets very well.
At the end of a session I just dump it into my hand and blow the paper target debris out and add the spent pellets to my lead collection for future casting.

Great idea but allergy to hay. Even though as a teenage bailed alot of hay. Something kids today don't do.

I use duct tape, but have many back stops throughout the yard made with just walmart bags filled with old Rags and Clothes In my garage I have a Plastic storage container with the walmart bags in back and on sides.







Also very portable. Easy to throw some in the truck and use one as a rest.

I like the pic w/the clipboard on it. Will use
That when I build mine. Thanks!

That is called the Silent Pellet trap. They use to sell for around $80.00, do not know what the sell for now. You could also buy it disassembled for cheaper. But if you can build one then I sure you can do it for a lot less. Good Luck.And that is duct putty in the trap.

Here ya go, if you want to build one.

Also you can make traps out of Rubber Mulch!

Been looking at different ideas. Rifle won't go thru 1 1/2in 2 x's., Duct seal and layers of carpet. Combination of each. Not sure. Will
Figure something out.

Metal trap used to be the bane of my vacuum when I lived in an apartment. Only thing worse than lead pellets were actual BBs. Trap would bounce them out of its maw over the (shudder) shag carpet. Had a cheapo poncho laid out to catch most of them, but the vacuum always seem to find more. Sigh.

For "misses" I had the trap in a $5 foam cooler (on its long side) that stopped them all on my luxury 7m, one Sheridan pump, range.

I’m cheap, well frugal, a triple layer of heavy fabric free hanging inside a wooden box stops 17 cal pellets and they collect undamaged in a bottle at the bottom. Replaceable heavy cardboard, Amazon Pantry Shipment boxes, form the front. Pellets are collected and with few exceptions reshootable. I do the same for Cowboy Quick draw wax bullets.
