Straw hay bales for backstop?

"JohnL57"I think it sounds like a mess when you have to dispose of the wet & moldy hay remnants which will be full of lead. The best use for wet moldy hay is compost or mulch, but I'd hesitate to spread lead in my garden. Maybe try a plywood box full of rubber mulch and backed with a steel plate?




Good idea John !!
Similar Pyramid Air concept (scroll to the end of article)

Above is a good read. Towards the end of the dissertation they describe the type of pellet trap I loosely copied. Their trap will even catch centerfire rounds as well as rimfire (theirs was larger than mine so exercise caution with a small'ish trap). Mine is mainly for pellets, and an occasional test fire of .22 rimfire.

What is needed?;
Bag of rubber mulch at Home Depot... Under $7
Ammo Can ( or plywood box as John mentioned)
Plastic cardboard (Coroplast) or similar membrane
Hole saw
Grinder with cut-off wheel
White Spray paint (optional)
Two magnets (optional)
Transparent laminating sheet (optional)

I'll let the pictures do the talkin;

Two I built based on their idea;





  • Rubber mulch does not have to be packed down to tight.
  • Paint the side of the can towards shooter with white paint for better "open-sight" sight picture
  • I cut the can opening about 1/8" smaller than the targets shown (targets measure 14cm x 14cm) just to keep the sight picture from getting cluttered
  • Put a strip of transparent laminating sheet from the left and right edge of the opening all the way out to the edge of the can (after it is painted white) to protect the paint from the 2 magnets that are centered on the vertical sides of the targets. That way you can drag the magnets off the edge of the can each time you change-out targets. (better than using your finger nails to pry the magnets off)
  • *** Note the curved steel "contingency-plate" placed in the mulch filled can on the left. That's the one that may see use for an occasional rimfire test-fire.
  • After about a thousand pellets (give or take) you can remove and mend the Coroplast with Gorilla brand duct tape, which actually makes it last much much longer. While you have it out a wood-framed piece of 1/4" hardware cloth sifter can separate the pellets, and the rubber mulch can be re-used


There may be better traps out there, but this one was fun and quick to build, and is dead QUIET !! (bonus)

This trap flat out works. Lead dust inside is now a thing of the past, since the pellets don't smash against steel.


 
"Bruce"I use a 16"x16" x24" deep card board box from Lowe's filled with rubber mulch. I have shot .177, .22, .25 and a .35 hatsan and at 15 yards nothing come through. I use duct tape to cover up the holes if they get to big. The only draw back to this is if the box gets wet, then you have to get a new box.
Hey Bruce maybe a derelict Igloo or Coleman cooler would work well with a suitable hole cut in one side. Waterproof, could be left outside in the rain, leave the drain open and any rain that gets in could get out.
 
I have a Rubbermaid storage tote that is about 12-15 gallon size. I have been using it for years. Filled with old jeans and welding jackets. I put a steel plate at the back just in case. I have even shot 200fpe big bore into it and they don't even make it half way in. I haven't emptied it in 3 years. It is now so heavy it is hard to lift. When I finally clean it all out, I will switch to rubber mulch.

AJ that is perfect !!!

You catch that Alli ???

Finally an idea that doesn't get ruined in the rain, and requires no pre-cut hole in the side, since the Rubbermaid is easily shot into.
 
Wow, fellas, thanks for all the great thoughts and ideas! I hadn't thought of the lead being left inside the straw bales but thanks for pointing that out. I think I'll skip on that idea.

I think the metal, or rubbermaid box, filled with rubber mulch will be a better idea. I have a set of metal spinners, so when I hit those, the pellets won't be going into the box at all (only the misses!). I will need to set this up so that I can see just which pellets hit better accuracy-wise with paper targets. 

Again, thank you all for the great replies.
 
"AlliInLL"Zebra, what kind of fiberglass? Like fiberglass insulation? Fill a box full of that and shoot into it? Any idea how deep it would be in order to work? And...where would one get kevlar?


Allison
Pretty sure the Kevlar would be serendipitous and effective if on hand, but pricey to source.

The fiberglass on the other hand... self loathing comes to mind. Would hate to think about opening that tub or handling any maintenance after it (fiberglass) got pummeled by countless pellets.
