Sounds supresssion tube thingies (not silencers)

[CrashInBlack]

I'm not sure exactly where to put this so maybe the Mods can help me out if this is the wrong spot. This is a link to a neat little video about Swiss gun traditions. In it is a shooting range where people are shooting with the tip of their barrels inside what looks like a 55gal drum lined with foam. They seem to reduce the noise very well. Anybody know what these are called, how they are made, and if they actually work as well as they seem to in the video?

Those are designed to reduce the muzzle blast from the rifles. They will reduce the noise somewhat as the foam will absorb some of it.

Video does not give you the true sound of gunfire. If you listen to the handguns right at the end they sound like pellet guns.

I couldn't see if they were using them but suppressors are very common in Europe. In several of the countries you can buy them right over the counter with no paperwork. It is considered good courtesy to the other shooters to use them.

Crash;

I seem to recall that Shooting Times editor Rick Jamison showed a device such as you're describing in an article he wrote, probably back in the 90's. In fact, it may have been that there were so many requests for information about the set up that they eventually published the plans.

IIRC, there was a discussion on here a while back.

Seems the barrels do work as far as making the range quieter to outside people, but for the person doing the shooting the barrels just enclose the muzzle blast right in front of him, making things louder for him.

It's just a silencer that has no method for attachment to the gun itself. Legal per the BATFE.

Bingo. The only outdoor range I know of around here requires shooters on the rifle range to shoot through them, and I stopped going because of it. If you're standing/sitting around the shooter, the sound is somewhat lessened, but if you are the shooter, it's not pleasant. And depending on the rifle, your brass can be deflected by the tube (or box, in our case) right back at you.

It also restricts the positions one can shoot from. At the range I mentioned, you can shoot from any position you want, as long as it's through the box - which pretty much means benchrest-style, since the boxes are attached to shooting benches.
