Lets See Ideas For Quiet Big Bore Ammo Traps

Jump to latest Follow Reply
Rubber mulch in a 18 deep 3/4 inch ply wood box by a foot wide full of rubber mulch has stopped big bore 45 texan 340 gr at like 500 ftlbs and 22lr as well at 2or3 feet away from the barrel had one ricochet because I hit the top into the plywood I didn't line it up well that day ever since I make sure I'm lined up to go into the mulch and it stops everything.
Thousands of rounds into it now

Just requires thick enough steel plate for the impact area . Big bore maybe 5/8 min?

Would sawdust work as an effective big-bore pellet/slug trap medium?

If you use enough of it, yes. Not as heavy, compact and "sticky" as rubber, but would probably be quiet.

Would sawdust fill in the void if you shoot in the same place for many shots?

I think there is room for a multi-layer backstop. So, making the outer layer cheap, or from available free material is a good idea:

Rubber mulch 6 to 8" deep; or sawdust 18 to 24" deep. Or ductseal 3 or4 " deep.
Sand filled carboard box, 6 to 8" deep, that you do not intend to need.
Steel plate that will stop the most energetic projectile that you intend to shoot, but that you never intend to hit.

What your trap should be made of does depend on what you are shooting. Penetration is not always energy dependent: Slow and heavy may penetrate deeper in some media. So, start with too much media, rather than too little:

I have some 'reusable' .51 slugs that I purchased from PA a while back (sorry, can't remember the product name)

Supposedly they can be reused if discharged into a soft enough target. Bundled scrap fabric was one of the suggestions. If it were thick enough and possibly backed with something to stop any pass-thrus it could be very quiet. I was thinking of doing something like this for backyard shooting....someday when I get around to it.

Bundled cardboard will also stop slugs remarkebly well if thick enough and is much quieter than whacking metal.

@subscriber I was reading here and thought I'd see if anyone on AGN has tried it.

Att. Ian; sawdust bullet "catcher"

Or anybody who has experienced an "oiled sawdust trap"..... I've got the above necessary ingredients basically running out my ears. I've been spreading waste sawdust on me and the dog's "training run"..... just to get rid of it. And because I'm an idiot, still change our cars/bikes/truck oils...

Oiled sawdust makes more sense in terms of stickiness and energy dissipation. Just do not use organic oils for finishing wood, as it may self ignite.

The link talking about saw dust for catching bullets speaks about 6 foot deep to capture them undamaged. I do not think this is what rubber mulch is for, etc.....

@subscriber It does, but I don't care about the spent slugs getting damaged after being shot. I'm also not pushing any airgun projectile 2000 fps, much less at supersonic velocities.
