how effective is a .30cal can at supressing .22LR?

[wcoats]

I'm looking into getting a suppressor right now with my original intent to use it on a .22LR. I am wondering about just going ahead and getting a .30cal suppressor(fully disassemble and serviceable for cleaning) so I could also use it on other rifles in the future. Anyone have experience with how well a .30cal can will suppress a .22? It should have plenty of volume, but have a larger gap around the bullet.

I just figure if I'm going to pay a $200 tax stamp and wait 9 months I might as well maximize the # of rifles I'll be able to use it on. Also 1/2-28 to 5/8-24 thread adapters are readily available.

I see that you know you'll need to be able to clean the can since you want to shoot 22 through it.

Most recommend a can in 22/45/308 but I understand that's a lot of coin.

To answer your question I think it would do a decent job, BUT it will also be a much bigger can. If I come the across the actual answer I'll try to post here.

It will work if you use a rifle it will take 2-3 rounds before it is really quiet. For a suppressor to be the most effective the air inside the can must be displaced either burnt out by firing the gun, a aerosol additive like the compressed air from a electronics cleaner or chemical additive like wire pulling gel or water.

This is what is commonly referred to as first round pop with a suppressor, with the .30 cal can you have more volume and that is why you will most likely have to fire several rounds before the can is working at max efficiency.

Only bad thing about wanting to do this is there are only a few manufacturers that make a user serviceable .30 cal can. .22 cans are becoming very common and really inexpensive.

A purpose built can like the SWR Spectre II will out preform a .30 cal can all day so if your buying based solely on price yes it will work in the respect that a oversize overbore can is better than no can at all.

yeah, it's 8" long instead of the 6" that the .22LR cans that he has. and it would have stainless steel baffles instead of the aluminum ones that the .22LR only can would have.(I can't afford the one with titanium baffles, lol)

Well, there is a shop locally that makes his own cans and has several for sale. His .22LR only cans are $250, his .223 or .308 cans are $650 with SS baffles or $1,050 with titanium baffles. Seems fairly reasonably priced so I figured I'd buy locally from him, but I'm not opposed to ordering one if there are deals out there that are enough better to justify it.

It should work fine. No need to have a 308 can that comes apart as long as it is all steel. Just soak it in the dip to disolve the gunk and lead. Make sure you wear gloves and dispose of the used dip (lead acetate) at a hazardous waste facility.

Most manufacturers will tell you to never shoot .22lr in a non-rimfire silencer. They are very dirty. At the very least, don't shoot lead.

Not to hijack the thread or anything but how does shooting a few shots displace air from an unsealed can?

 

[Arizona_Mike]

Running a supressor wet has nothing to do with displacing air (or oxygen) depending on the first-round-pop theory being quoted (of which I am highly suspicious since air diffuses very raidly).

Water or jell cools the expanding gasses due to latent heat of evaporation.

An unsealed can has end caps that thread on tightly, so all of the gas flows out the hole in the front end cap. The oxygen is displaced by gun powder gases and the distinctive pop is eliminate after the first round is fired.

Oxygen is a flammable gas, when the unburned powder and gasses following the bullet hit air either inside a suppressor or at the end of a unsuppressed barrel all those gases expand rapidly (explode) this is where the bang comes from.

When the oxygen is displaced with a inert gas, say the gasses from a previously fired round(s) the suppressor is more effective because the gasses will cool inside the can and it becomes more efficient. When the volume of air gets displaced inside your suppressor no matter if its sealer or user serviceable there is less oxygen that must be "burnt up".

If you still don't believe me take a suppressor out really does not matter what caliber or type but .22 will usually work best with subsonic ammo. First shoot 5-10 rounds video it, then take suppressor off purge all air from it it will take about between 5-15 minutes depending on design so say 30 minutes just so no gas is still inside if you have a air compressor blow it out with that, now if you or someone you know smokes have them blow the smoke inside the suppressor 2-3 times until smoke comes out of both ends and then shoot the same gun with the same ammo and video it from the same position.
