Title: How to quiet target shooting with PCP
Post by: oakey on April 21, 2013, 03:34:45 PM
The back stop? Little hard to create a sand pit in my yard. Clay is expensive and dries? Any other ideas to stop the Thud of higher grain pellets being tossed down range at high Velocities?

I've just finished a small version of "cyclonestop" version 1. I'll put some pictures up tomorrow.
Basicly it's POM/PVC plates in an angle to each other and some rolled sheetmetal as a cyclone in the back.
More quiet than I thought...

I shoot at PVC almost daily, it is LOUD.  I hit it from 100 yards away and it sounds like a baseball bat. 

Oakley, I would think about using multiple layers of cloth behind the target then a harder end piece.  Maybe even something like sound deadener that has a foamy texture.

Duct seal works good, but does cost.

Old rags (a bunch of them) works. Old carpet.

Sand or dirt or mulch filled bags. Won’t last as long but duct tape will patch the holes.

Any kind of walls (the deeper, the better) you put around your back stop with help bounce the sound back towards you.

Mine is made from "junk" but it's reasonably quiet. Can usually trash-pick and collect the stuff needed as i walk the dog every day.

Box
Stacked carpet cut to fit in box (usually trash-picked carpet)
Front of box cut out with a layer of foam rubber facing the shooter.

Layer of foam rubber has no chance of stopping the pellet, but it does deaden the sound of it impacting the stack of carpet.  Move the targets around the face and change the foam rubber part often as pellets tend to chew it up. For really hot-rod guns, will set a stack of bricks behind the trap just incase.

Get months of use, then will just take it apart, toss it, and make a new one.

Go to Home Depot and get some rubber mulch. Fill a bucket, box or whatever you want to use. It's cheap and it's quiet. It won't dry out either

That's on the list for the next trap.  Will still cut out the face of the box and add a foam rubber or carpet face as the noise the the pellets smacking the cardboard is louder than the shot.

I may have to buy some mulch for a low-profile and quiet backstop for my shop that I have in mind.  Has anyone tested how many inches/foot pound energy required to stop a pellet well in front of the back of the container?

I got a wild hair one day and decided to try a 21gr cuda out of my marauder at point blank range vs my duct seal trap. Im tuned for 30 or 31 fpe, it went through 2" of duct seal and severely deformed the metal containers "safety layer" of thin steel sheet. When i usually shoot, (30yds or more) the duct seal soaks up all the energy and stops the lead before it hits steel. For rubber mulch, i would guess youd need somewhere near atleast double yhe thickness of ductseal. Since that rubber mulch is light and fluffy (lowdensity compared to ductseal) id guess 4 inches should put a stop to anything under 30fpe. It also depends on how exactly your containing that mulch stuff and  how tightly your packing it into its container. :) personally, id just go with an inch and a half or 2 inches of ductseal and call it a day. I think i payed about 2$ a brick and used 10 or so for my giant trap. Should last me the better part of a lifetime of shooting, only trouble is, man!!!! This thing getsdarn heavy! The more you shoot it, the more weight it gains. My 25lb trap is 2yrs old and shes about 35 lbs now, haha!

Just read where someone used old polyester fiber filled bed pillows in a cardboard box with duct tape on it.

Quoted from Woody67 on the CAPOF:
"A few weeks ago I decided to get a couple of new pillows, and get rid of 2 pillows I had that were filled with polyester filling, not feathers.
Instead of throwing them away, I folded them up as tight as I could and stuffed them into a cardboard, then taped it up. Thumbtacks are great for holding the target, especially with the tape on the cardboard.

Anyway, I used the box yesterday when I zero'd in a new scope on my .25 marauder. I was shooting @ 25-35 yards, and not one pellet was a pass-thru, which surprised me.

This morning, curiosity took over and I took the pillows out of the box and found that hardly any of my shots went through the first pillow (A few did and got stopped in the second pillow), so I decided to do a little test.

I took both pillows, and set them on top of eachother, then stood them up flat against a 2x4.
I shot a 43 grain Eunjin pellet, muzzle @2ft from the pillow, using the Mrod...and the pellet didn't even pass through the first pillow.

The poly-fil fiber grabs the pellet, and absorbs all of the impact almost immediately. What you end up with is a pellet that has a big ball of fiber around it. The pellets have absolutely no face damage to them either. The only markings are the rifle marks from the barrel.

So, at almost point blank range, at 2k fill...a poly-fil pillow stopped 40+fpe! That's only about 2 inches of fiber."

I like the pillow idea even better for an indoor backstop. You can find cheap pillows pretty easily and the box would be pretty light, too.

I use an old phone book wrapped in a layer or two of old carpet. Works well for me.

Holds paper targets and stops pellets and the price is not bad.

Great ideas guys. Thank you. Clipboard and rubber mulch are fantastic.

Bought the rubber mulch then when I saw the Duct-Seal I changed my mind it's perfect! Picked up 10 pounds of duct seal gonna stuff my 22 rim fire trap full of if it! The quiet back yard.

Thanks everyone for the help.

Oakey : As I ponder HPA, I would be curious how this holds up for you and how often you need to change out the duct seal.  (i realize it may  be a month or so before you know depending on how many shots you take at it)

 Thanks for any insight you can provide.

There are folks who shoot regularly and have used the same ductseal for year's
