Why the baffle change from .22's to... everything else?

[gun'sRgood]

Recently a gun magazine ran a fairly extensive article on a bunch of suppressors. They had X-rayed a field of them. It seemed that the .22's had a radical different design than all the others. The others seem to be mostly stacked cones in a variety of size and space. Why the difference?

Was that article online or in print?
I would like to see it, because suppressors and radiography are of interest to me.

Yeah, same for me. As a critical care RN I got to experience several types of radiology. Working as a lab tech. on a government test facility I got to see how powerful this stuff can be. I don't doubt that soon you could take a pic of the ground and see gold or whatever you wanted to look for. Most of the magazine's article was a bit superfluous, but the radiographs were very interesting. Now! Where in the world did I put them?!?! I think there were about four full pages with each suppressor given a brief review of ability, pro's and con's. I'll start the search.

Some time ago I saw a video of a transparent suppressor with a super high speed camera.
Seeing the gasses as they expanded and how, was incredibly interesting.
Of course it didn't hold up very well... the acrylic or whatever wasn't strong enough for repeated use but still great while it lasted.
It might still be on YouTube if you wanna see it.

Why the difference?

Because gas flows differently at different pressures. The tight baffle stack of a rimfire can would trap too much gas from a centerfire and could burst.

Wait, I read your post wrong. All my rimfire silencers are cones.
Some radial, that is bell shaped,

some are just cones and spacers, and some are cones with attached spacers that look like a witches’ hat.

My Blackout can is K-baffled, which is a cone with a flat plate at the point end. The opposing sides are cut for porting.

What kind of rimfire cans are you seeing?

That guy's channel is called Smarter Every Day. It was an interesting video.

I'm one of the lucky few: I have a fair collection of suppressors AND I am a radiographer. Here are ten of my .22 suppressors and the radiograph (which is a composite of two exposures

I also have one reflex suppressor, also for .22.
There is a thread on it here: UK Custom Shop Limited: Wildcat Predator 12 (for .22) | The High Road

OK, I gotta find that. I'll be back. Thanks guys!

Some do, some don't. We use the same cone type baffles (although not the exact same design) in our 22TD as our centerfire rifle cans and the 22TD is very quiet.

Monocores are typically done because they're cheaper; more material efficient and quicker to machine with minimal assembly as compared to stacked baffles or welded cans. My 8" Accipiter burns up nearly 2 feet of bar stock, the baffles and blast chamber are quite a bit of CNC turning, and a lot of time is spent assembling and welding. An 8" monocore uses 8" of material, a subspidle lathe can do the simple profiling, boring and threading in minutes, and a VMC can carve out the " baffles" very quickly. A millturn or 4+ axis turning center can do it all and spit out a finished core that just gets a tube and a cap.

At any rate, there are lots of baffled pistol and rimfire cans. Some use conical baffles, some use radial cones, some have K baffles, a few use M baffles (a conical or radial with a "backwards" skirt).

I use conical baffles for everything except one-stamp integral rimfires because a monocore is really the only way to make them serviceable without being SBR. Otherwise, I avoid monocores entirely because outside of .22 rifles, they suck. Played with them for a long time trying to build a better mousetrap, eventually had to throw in the towel.

I don't even have a 22, but I want to build one around that can.

That's AWESOME...!

Wish my ice cube trays were full of those "cubes".....

Super awesome. thx!

Found some bad pics of those x-rays. Here ya go

It's the last "way too long" variety that I see fairly common for the .22

I can't really think of a better system for small parts like these. I tried mini muffin tins, too, but the ice cube trays are more space efficient, and safer for the parts being plastic

Still looking for the original pages. Found some bad pic and posted them. Definitely interesting.
