I'll be moving to a new house on 10acres and will be able to shoot 400yds. I don't want to anger the neighbors and was wondering if anyone had any ideas on how to suppress the bang! without having to build embankments or plant hedge rows of trees. My 1st thought was to make a 4'x8' box lined with heavy insulation and covered with peg board (all this would be interior). Think this would work? Any and all suggestions are more than welcome.

Years ago there was an article in the American Rifleman with design specs. for a silencing box for indoor use. As I recall, it was very much like what you are describing. According to the author, it worked very well to attenuate the muzzle blast. I believe indoor ranges became controversial when air tests were conducted by the N.R.A. and others. It was determined that firing indoors without the proper air exchange was not advisable due to elevated levels of lead and copper in the air. I don't think I would worry about that if I was doing a very limited amount of shooting. I would make sure it's legal to use a muffler/suppressor though.

Would love to find those specs, as for air quality, all shooting would be done outdoors. I'm in a TWP and have been shooting there for quite some time and decided to build. In the mean time a new house was built and the lady said that it can be annoying. I'm just trying to keep the peace and still be able to walk out my back door and shoot on a range. I'm not looking for total silence just something to take the bite out of the blast,

OK, here is a "silencer" which Rick Jaimeson, a former writer for "Shooting' Times" magazine, said he used on his property to cut down the noise. He took a number of TIRES.........just the casings...........No tube or rims ;D He lined them up in a row.........don't remember just how many he used, but I would suspect somewhere around twenty or so? I would imagine the more the merrier. I suppose I would kind of line them up on some sort of a plank and you would have to devise a way to fasten them so they would not fall down A little ingenuity here would help. In effect, you have created a series of "baffles" just like the silencer you would buy or make for a gun. While you will not eliminate the "super-sonic" "crack" down range, it will arrest most of initial "bang!" Hope this is what you are looking for. Richard

now there is an outstanding idea. thanks richard. I think tonight i'll start collecting tires. First stop will be the lady next door, she has 2 cars so that'll be 8. LOL!!! Seriously that is a very good idea.

The tires would work pretty good I would think. Tires would absorb some of the shockwave instead of being a reflector like a metal drum and would be more like a baffle. We used to use a concrete culvert at a range once, mainly to limit muzzle direction but as a secondary effect to cut down the noise. While it really reduced on the sides, being to the rear wasn't pleasent. Muzzleblast shockwave, You could probly get semi-truck tires given to you. Those would have a 22-24" rim/inside diameter but would be pretty big to be easily movable compared to using smaller tires. You may want to drill some drain holes in the bottom to get ride of water. I can imagine the first shot blasting stagnant mosquito larvae infested water all over you. Again it would control sound to the sides but not that much to the front and rear. Maybe some creative landscaping with embankments covered with evergreen shrubs would also be a big help. I have one cowboy shooter nearby that shoots steel plates out to 200yds and since the targets are closer to me I hear the target hit before I hear the muzzleblast so perhaps some evergreens around your backstop may also be advisable.

The plastic shooting tube is pretty awesome. The 24" drainpipe will cost you about $20 a foot if you bought it new from a dealer.

A few tidbits on noise and attenuation. Most sound waves are not attenuated, they are merely redirected.
Cutting edge technology is a rubber sheet embedded with metal particles. The sound waves hit the metal, cause it to vibrate, in turn the vibrating metal causes heat. Sound waves to heat energy...true attenuation. Kind of like the steel belts in a tire.

It could cut down on their noise and solve the energy problem at the same time. ;D There was a post a few years ago on another forum in which a guy was looking for this same information. He was told by one of his Army buddies that there was a range silencer which was made from two 55gal drums connected end to end. Something was inside of them but the guy did not know what kind of dampening system was used. I joined a club simply because of a neighbor whining about my shooting. Seems that every time I shoot, her house dogs start throwing a barking fit. About the time she gets them to shut up, the 10MLII goes off again, they start in again, etc., etc., yada, yadda yadda.

I was watching the Maximizing your Muzzleloader video by Russel Lynch and there was a shooting sequence he done at a range. It was a covered bench with a dirt berm in front of it and the gun was shot through the drain pipe (I dont know, thats what it looked like) in the berm. The berm appeared to be about 6 or 8 feet wide and the pipe was a little longer, of course. I will try to find a pic or u tube vid and post.

That looks more like a safety set-up much like we had but we had to have the muzzle in the culvert. Shooting thru the tube pretty much limits where the round can land.
I shot at a civilian range in Europe where you had basicly a 12" gap to shoot thru that was about 30-40' from the muzzle. Reason being right behind the target berm was a apartment building. Fairly nice range with good benches then if you wanted to shoot prone they had these tables you laid on so your shooting at the same level.

ADK.............A great idea! Let me add another possible addition to your "contraption ;D" I used to belong to a club up in NJ that was forced to go "underground" due to urbanization. The club subsequently built two under ground concrete pipe tunnels to 100 yards. A bunker was built at one end with benches to shoot from and a enclosed impact area at the other end. By the way, this is also EDGE's club. As smoke can be a problem, they installed a fan mounted............I think.........about 25 yards down the tunnel. The actual fan was mounted above ground with duct work down to the tunnel. This greatly aided in removing a lot of the smoke. An additional exhaust fan was mounted in the top of the bunker also. Your contraption might also benefit from a fan near the far end also. If no power is available, possibly a car battery or solar panel could provide the power? Just a thought! Amazing the ideas that people on this board come up with. Richard

It wasn't my invention Richard (wish it was) but if you insist on giving me the credit I'll take it. Dannaboone, your definition of attenuate is too complicated for me. I'll just go with "it cuts down on the noise". ;D

Problem is that all the guys I shoot with now are such old dudes you would have to wake them up to get them off the table for the next shooter.
