    Default DIY Silent pellet trap

    I have a Sumatra 500 and a Artemis PP700S-A but getting to plink in the back yard is becoming a pain as both my PCP's have silencers but the 6mm metal plate I use for a backstop is making quite the noise with impact. I searched the DIY thread and decided to make a silent pellet trap.

    Material used:

    - 4mm 250 x 250 metal backstop x 1 - R45
    - 25mm Aluminium angle bar x 2m - R130
    - Plastic compound x 7 packet, this was sourced from Voltex - R75 x 7 = R525 Not cheap at all
    - 250 x 250 3mm masonite - Had some laying around
    - poprivits
    - self tappers x 4






    I framed the 4mm steel backstop with the aluminium angle bar and then made a second square from the aluminum that fits snug in the first and then cut the masonite to fit inside this square.





    I proceeded to fill the first "box" with the plastic compound and then closed the "box" with the lid making sure the masonite is placed on top of the plastic compound.


    I then stood on top of the box to ensure the plastic compound is properly compressed. Clamped the edges with G Clamps and drilled holes in the sides to lock together using self tapping screws.







    I added two paper clamps to the front to attach targets with.



    and also added a footplate to help the target stand at attention



    Now for the test to see how it holds up to the task.

    Would be interested to see how that plastic compound holds up?

    I tried the Polymag Predator 16gr pellets from the Artemis PP700 5.5mm from about 3m away. The small hole was a .177 from about 1.5m, also polymag Predator pellet.

    I had a bit of time and pulled the Sumatra out.
    Shooting the JSB 25.39 gr pellets from 20m and grouping 3 shots at high velocity and 3 shots low velocity





    This is at lowest power, for once I think the grouping was a tad tight








    17mm penetration

    These are the highest power setting







    26,5mm Penetration on the single bullet hole. This is measured to the back of the pellet and pretty much stopping against the backstop plate.

    It is definitely a quite pellet trap as you only hear the pellet's impact on the masonite.

    In short, I am very happy with the result.

    Rubber mulch in a cardboard box works as a cheap quiet pellet trap material. It is basically ground up car tires. Don't know what it is called in SA. It is sold and used as ground cover in the USA.

    Will look into the rubber mulch. Sounds like good idea.

    You will need a much deeper layer than the duct seal or electrical putty, but it is much quieter.

    The putty tends to grow a hole all the way through, if you keep hitting it in the same place. That is why a steel stop plate is a good idea. The rubber mulch is not completely immune from developing a through "channel", although it tends to be "self healing" as the chips cave into any channel as it starts to form. Certainly, a little shaking and tapping will settle the mulch to close any significant cavities, while the putty requires serious manipulation to fix through holes.

    Six inch deep compacted mulch will stop any 30 ft.lb pellet. I like to double that just to be confident that nothing get through to the backing plate, ever. You could experiment to find the threshold, but the thinner the layer, the more likely that a pellet will find a channel. With a thicker layer, the agitation of subsequent shots keeps caving in channels before they can reach front to back. This in contrast with putty, that is rather rigid by comparison.

    Very hard to find rubber mulch in SA for some reason. Tried a while back and the only place I found was an equestrian supply company that uses it on show jumping grounds for shock absorption. They completely ignored my enquiries, likely as I didn't want 6 tons of the stuff.
    If anybody does find a source, please let me know!

    Some of these companies actually grind up old tires in SA: rubber recycling Companies and Suppliers in South Africa | Environmental XPRT

    Some of them probably have small bags of this stuff for sale.
