backstop

[dave77]

At least temporarily I'm going to be using my garage wall as a backstop. Will a piece of ½" OSB stop a co2 .22 pellet. Will eventually get or build some kind pellet trap but for now will just attach a piece to the wall. I could go thicker if needed but already have some smaller pieces of ½ OSB, hate to buy any lumber right now, was at Lowe's yesterday, $8.50 for a 2x4x8.

Only one way to find out. I bet it will stop it until it gets beat up enough. In the long haul I would recommend a steel trap. Not only will they stop the pellet but they will also prevent ricochets.

Ditto on the steel pellet trap. The 22 rimfire rated ones will work with any airgun and you'll never wear one out. Just pick it up and move as needed. Only issue is lead splatter under the trap, but that's an easy fix. I use one in the basement for my indoor shooting.

[dave77]

Was looking at this trap, only complaint was some pellets bouncing out but that a piece of cardboard behind the target was enough to stop them. Will build a shelf on the garage wall and make it long enough to put some silhouette targets on it.

Unfortunately I have no basement and I don't think my cats would appreciate me shooting indoors.

Can you shoot outdoors? You could back up the OSB with some thick rubber stall mat. Some of it is 3/4 inch thick and comes in a 3x6 foot piece and smaller.

The pellets out of my Weihrauch go right thru osb board. Im not sure about the CO2 gun you are getting.

[dave77]

I will only be shooting outdoors, at a outside wall of my garage. New gun is rated at 550 FPS. Just looking for something temporary, maybe double up on the OSB for flyers and mount the actual target on a short piece of 2x12 I happen to have. The stall mat is a pretty good idea, 3x6 would be a good size to back up the silhouettes I want to get, that would give me a 18" above and below the shelf I want to put up. Maybe a larger piece of OSB behind it just in case, the garage wall is OSB and I could always patch it with some wood putty but would hate to have a pellet flying into the garage.

I have the Walther Co2 Lever rifle that shoots .177 pellets in that speed range. We are going to have some nice weather next several days and I will do a test for you. I have some OSB board and the mentioned stall mat. My thinking was to place the mat behind the OSB. Not sure if a pellet will ricochet of the tough rubber mat but will find out. I do know that pellets will ricochet off those rubber self sealing targets for .22 rimfire!!

I used the stall mat to back up a sand filled box made of 3/4 OSB for a bullet backstop at my range. 2x4 foot box 16 inches in thickness full of sand.
The stall mat even with bullet hole would self seal and keep the sand in. Even a .308 rifle or .45-70 would NOT penetrate the box!
4 yrs. later that box is still holding sand even thought the center of the OSB is fully shot out!

[dave77]

Thanks, looking forward to seeing your results. Hoping to get the gun by end of this week or sometime next week.

I think your design will work okay with a 500 fps gun. At that velocity, you have a lot of options for making a temporary backstop. Have even heard of some shooters stuffing a large cardboard box with shredded paper and such.

I worked at a lumber yard for 10 years. If there is one near by, go there and ask if they have any ( cull ) lumber. Cull is lumber that is warped, broken, chipped or damaged in some way. They will gladly sell it for pennies on the dollar.
I would recommend a piece of Advantech flooring board. Much harder than OSB. That is what I use outdoors for my air rifles shooting around 800 FPS.
It would take a long time to wear it out.

[dave77]

Ouch, $73 a sheet right now. Think I will use what I can scrounge up around here until lumber prices come back down (hopefully they will). Have some other projects I will need lumber for, need new, real simple steps for my front porch, 4 steps and railing on one side, I'll bet it'll be over $200.

For your permanent one, consider making a silent trap from a 5 gallon bucket and lid. Line the bottom with an inch of duct seal (clay) from Home Depot. That in itself may be adequate for your low powered rifle, if not, fill it up with rubber playground mulch.

Mine will stop a .25 cal 28 gr pellet at 825 fps (40 foot pounds). Only a third of them make it past the rubber into the clay.

Yes, Advantech IS expensive. I would not buy a new sheet right now either. That's why I mentioned checking with a lumber yard for Cull...( damaged ). They might even just give you a piece large enough for a backstop. Heck, thats what I use. The piece I'm using is only about 18" x 24". I lean it against the brick outside my house. Then in front of it, I stick a cheapo wire sign holder in front of it with my target hanging from that. Works perfectly. My setup didn't cost me a penny, except for the targets.

[markiver54]

IMO...do not use OSB. If you do though, just double, or triple it up.

[dave77]

I've got a piece of ¾" OSB I can double up if needed for flyers. I have a piece of 2x12 to attach a paper target to, I don't think a pellet is going to go through that. Will do something more permanent later. I'm thinking I will order this and attach a shelf wide enough to set it on along with some silhouettes with some kind of a backer behind the shelf.

[markiver54]

Now that sounds like a good plan.
When we were talking OSB, I was figuring you were talking about 7/16. What you're going to do certainly sounds adequate. ☺

[North Country Gal]

Dave, we just use a 4x8 sheet of plywood as a backer to protect the wall in our indoor 10 meter range. Even our most powerful air guns at that short distance can't fully penetrate it and do damage to the wall. Anytime you can angle a backstop, you decrease potential penetration.

[dave77]

My rifle has shipped, supposed to be here Saturday. Pellets and CO2 from Amazon are also supposed to be here by Saturday.

[markiver54]

That's exciting...have fun my friend!
