That's a damn good post. I knew a .22lr was no joke, but shit that was one hell of a test.

I may start carrying my Sig Mosquito as a backup.

after seeing this post, I'm thinking of getting one with a suppressor, but it will have to be a "Next Year" project..

Doesn't suppressor slow down the bullet?

I would think so.. will need ss1 to chime in... but I would think at 100yrds it should still have plenty of punch

22LR pistol with a suppressor will go MUCH slower than a 22LR rifle without a suppressor.

Longer barrels allow for higher velocity. 22LR is pretty slow out of a pistol. People have posted similar tests with 22LR pistols and say the range for adequate penetration from a round fired out of a Walther P22 is 8ft. Which is pretty accurate with all the 22LR mini revolvers that have been used. Only time they were reported as lethal was when shot at nearly point blank range.

why you got to take all the fun out it...

Not taking all the fun out. A suppressed 22LR pistol is still a good tactical trainer as long as it isn't the Walther P22 (because it weighs nothing and isn't a realistic trainer in my opinion).

I have had my suppressed p22 for years and tha is the main training gun i use for newbies...never had a single issue with it..and it has been over 7 years with 3000+ rounds through it

What slows down a "speeding bullet"? Drag/friction. Most modern suppressors don't impart direct friction as in wipes or a spud, but I'm not so sure about adding drag thru pressure. It get's complicated with gas density. I would imagine that the expanding gas behind a subsonic round as it exits the crown of the barrel and into the first chamber of the suppressor is going to fill the chamber rapidly creating a more dense atmosphere. Before the round passes into the second chamber the question is if there was enough of a pressure increase to create more drag and so on in subsequent chambers. Then you have the sonic wave with supersonic ammo and the pressure there as well. I imagine that most modern manufacturers "tune" the can in terms of gas flow and volume to minimize the impact; however, I'm sure there will always be some. For example, one of my AAC cans is designed for the shooter to adjusted the point of impact by rotating in 45° increments. So there has to be some element of pressure impact on the round. How much I guess depends on the ammo and the can.

As they say when in doubt ask C3PO!

Depending on the volume of each chamber in the can it can decrease the pressure behind the round which negates the added length the suppressor provides.

The longer the barrel the more time which the bullet has pressure behind it. The longer the bullet is under pressure within a barrel the faster the velocity out of the muzzle. This is why SBR's have slower muzzle velocity.

With a suppressor, there is a pseudo amount of added barrel length. But if the can has large chambers too much pressure escapes from behind the bullet. If you make the chambers small and narrow, less sound is dampened and less muzzle flash is contained.

The angle of the chamber walls can improve sound attenuation while you need enough total can volume to contain the gas/blast exiting the muzzle so it doesn't report out of the front of the can.

That's pretty much all I've learned about cans. Would I be able to design a compact and highly effective can? No. I could probably make a bottle silencer though. lol

i have known they were good for years since i learned the Israelis have used them in pistol for assanations and crowd control as stated in the article. but his testing was pretty cool.
