What about stacking some round hay bales outside the window? Im thinking 2 rows stacked 2 high in each side.
What about stacking some round hay bales outside the window? Im thinking 2 rows stacked 2 high in each side.
Back in the 90's I shot in an evening winter 10-22 50 BR group league. We shot from within the clubhouse with barrels extending out shooting ports.
This range is located in a setting with houses within 1/4 mile of the range.
In order to muffle the muzzle blasts one of the members built two 8 Foot x 16" x16" tubes lined with carpet that was waffled up about two inches in each direction, kind of like waves within the tubes, mimicking suppressor baffles. These tubes were set up outside the shooting port tight to the building
IIRC there were caps on the ends of the plywood tubes that reduced the entrance and exit holes somewhat like a suppressor however the holes were still quite large......maybe 10-12 inches.
The net result was the tubes very effectively reduced the muzzle blasts from subsonic ammo.
However I seem to recall that the plywood tubes could not sustain the muzzle blast from center fire......they quickly began to come apart at the seams.
Thinking back on it now, 55 gallon drums may have been a better option.
If you shoot a rifle with the muzzle inside a small room, even sound dampened, watch out for the repetitive pressure blast on your eyes. You will have to wear ear plugs AND ear muff to protect ear and brain from concussion (human skull is very thin in ear area).
Think ventilation to avoid breathing primer and powder fumes.
The already mentioned car tyres tunnel aka giant silencer is an excellent concept. Use 2 metal 200 liters barrels (sorry I am metric) opened at both end, fill them with used tyres, weld/assembly them well aligned and place them on a support outside your shooting cabin.
Using some ventilation to increase air pressure inside the cabin and naturally exhaust through the "silencer" will keep you safe from fumes.
Here we have plates made from very small pieces of used tyres, glued together. They are usually used as "pavement" in schools to protect kids falling in playing area. That makes an outstanding firearm noise dampener. The ones I have seen in use are approx 10"x10"x2".
An underground tunnel would solve a lot of problems.
My shooting shack is uninsulated. I have small windows on each side and in front, and an inside bench. I have berms at 40 and 80 yards. I put two blue barrels together. They are stuffed with insulation with about a 10 inch hole all the way through. I put the muzzle out the window and into the barrels a bit.
This all faces away from my house which is about 80 yards in back of it. The range is in the woods. When I touch off anything centerfire, my wife says the windows rattle in the house. A .22 WMR makes a pretty sharp crack. Subsonic .22 match rounds are very quiet.
I limit my centerfire use to checking zero on guns I have a question about. My neighbors are not close, but they are all nice and I don't want to tick them off. I have one neighbor that I call double-tap man. He must spend a fortune on ammo. He shoots for hours on end, generally on nice days when you want to be outside or have your windows open. I don't want to be that guy.
In short, it's nice to have an "in a pinch" range and one for .22's but it was not the glorious trimph I was hoping for. On rainy days, I hunt from the porch. I hunted from inside once, fell asleep and woke up to a deer in front of the 80 yard berm and moving. I up and fired. No ear plugs and the muzzle inside. Big mistake. My right ear used to be my good one. Now it's the bad one. DO NOT do this.
I still drive 90 miles one way to get to my favorite range. I take 3 or 4 rifles and a sandwich and make a day of it.
I once visited the home of a young digger whom I supervised (as a Warrant Officer) and he showed me his garden shed where he practised playing his drums. The shed was made from pressed metal.
The shed was lined with cardboard egg cartons glued to the walls and ceiling and I stood outside while he gave the drums a few rolls and could barely hear a sound. So worth considering for the internal noise issue.
I gave him a big tick on his annual report for his ingenuity and also for his consideration for his neighbours. He made corporal within a year.
I like smart people.

[QUOTE YOUR NOISE IS ONLY AT MUZZEL MAKE PARTIAL ROLL OF HEAVY FENCE WIRE TO LET YOUR REST SET RIGHT WITH STRAFOAM WRAPED AROUND IT YOU GET A LITTLE DUST AT FIRST BUT REALY CUTS NOISE=josh shrum;839261]I am thinking about building a shed to practice from, but with a slight twist.
In an effort to keep folks from hearing/knowing I am shooting I want to to keep the muzzle INSIDE the building to prevent as much noise as possible from escaping. I likes my privacy and don't want neighbors nebbin'.
If I go forward with this plan I would fence in the range (100 yards) to keep folks, pets, etc from wandering into my field of fire.
So my question is:
With sound proofing the walls and ceiling, baffling in front of the muzzle, carpet on the floor, ear plugs and muffs, is my idea safe/viable? I am thinking along the lines a of Jam Room that a lot of musicians build, something with sound proofing to keep sound in as well as baffling to keep sound from blowing up my ears.
Almost an anechoic chamber, except I will need at least one opening for the bullets to go through.
In addition, I was considering planting some species of Thuja/Arborvitae around the building, possibly the entire range, in an effort to reduce noise.
I would welcome any concerns and/or suggestions.
Thanks!

hay bales shot with stucco in a color to match the land scape
hay sounds great. if you find a farmer that stashed a bunch and did not sell for a couple of years, you can probably get it for free. hauling might be a pain.
