Wartime, home made silencer

Suppressors are a number of principles and when applied they usually work to an end. How effectively depends on how many rules you break during construction. Steel heats up and expands and contracts, doesn't cool readily holding heat so there are better metals to use. You don't need an alignment rod, all internals should be a tight fit. Today's "J" baffles and "K" baffles have done away with many outdated practices. The can should be assembled and you should be able to carry it until needed completely assembled. There are many small things to know about these, there are complete PDF about it on the internet...easier than writing the whole thing again here. Call up a picture of "Sonic suppressors" on the internet and the pics will show you many things that will make it easier for you to grasp...

By the way, there are many fables about suppression that shouldn't be believed. Look at the pics, you'll get it...

I remember as a kid my uncle had a Mossberg Sound Moderator made for a .22 rifle, I always wanted to own it but over time a gun tinkerer friend of his talked him into letting him try it out on a .22-250 he was building up for ground hogs. That once coveted item is now just a straight empty tube with no forward end or internals. I wish they would legalize them here, I have seen suppressed Ruger 1022's at the National Gun Day show in Louisville Kentucky and would love to own one. Back in more sensible times before the city moved to the country I used to shoot my AR15 back in a friends bush, try it today and within minutes there are police cruisers circling the block.

The suppressor your uncle owned was for a .22, there would be no sensible one for e 22-250 as the bullet will give you as much sonic crack as a rifle will. Also muzzle pressures would clean the insides out. There's a company in NZ that builds cans for about any rifle you'd like, have a look at their site... Gunworks Ltd - Suppressors Accessories Even the Maxim silencer for the 1903 rifles were just a sound moderator. Some of these are better now though, things have come a long way. Ruger offers their 10/22 and pistols with integral cans now. I saw a picture of an IDF soldier nested down in a pile of rubble on the Gaza with a 10/22 and a VERY large optic. I'd think he was doing eyeballs at reasonable distance...

I think the suppressed 10/22's I saw were made by Cieiner (not sure of the proper spelling) They just looked like a bull barreled rifle to the untrained eye.I wish the guy that ruined my uncles moderator had left it be. You still see the odd model 1890 or 1892 Winchester and some Mossberg .22's threaded for the Maxim moderators.

Possible... Here's more reference what I was saying. Israeli Ruger 10/22 Suppressed Sniper Rifle

Suppressor design (despite what some manufacturers would have you believe) is quite simple and is just a combination of good baffle design coupled with sufficient internal volume to absorb the muzzle gases. Some baffle designs are better than others but none are 'magical' and even plain washers will do a good job in a proper design. The manufacture of a good suppressor needs to be accurate to ensure correct alignment with the bore, and robust enough to take a moderate knock.

Suppressors are a number of principles and when applied they usually work to an end. How effectively depends on how many rules you break during construction.

Two people discussing what they've built over time may disagree about specific details but if their general principles are the same it will work. Sub sonic ammo is mandatory for quiet and quiet is only to make it "Not sound like gunfire to people used to hearing gunfire"... A bolt action is best. All the gasses are contained that way. Yes, self loaders get extremely hot. Then they get loose and when you tighten them and they cool, you need a pipewrench to loosen them.
