Re: St Louis couple in mansion has guns seized

The prosecutor essentially displayed her prejudice in the case 2 days before the gun was confiscated, when she stated at a press briefing that she would do everything in her power to ensure that the couple did not get away with "this" whatever "this" is in her opinion. From various reports I've read...

Re: Removing lead fouling from aluminum bells

Doesn't seem very thick, so probably not affecting suppressor air volume significantly. It's ugly, but you don't have to look at it in use. If it were mine, I'd coat all the fouled surfaces with lithium grease and shoot it. Suppression improves slightly (though with a bit of smoke), and the white li...

Re: Removing lead fouling from aluminum bells

Are you trying to get it clean for some reason or simply removing buildup to allow reassembly with most of the grime out of the way? If you are trying to get it clean what is the upside compared to just getting it sort of clean? This is an important point. It's hard to remove the base filth from al...

Re: What we should do about the riots

Sure. They'll probably go that way with it if they can find a couple of witnesses to confirm Chauvin's animosity. I don't care much at this point. It's all become such a mess, so many hurt and dead as a result of the rioting, so many businesses destroyed. What a waste.

It seems from the latest information I've been able to glean that George Floyd had recently tested positive for COVID-19, had a quantity of fentanyl in his body, had dropped a small ziploc bag full of white powder or pills as he was cuffed and squatted against a wall during the initial arrest, and h...

A well thought out statement, and if it could work that would be wonderful. Unfortunately it seems unlikely to happen. That's because in general we know that the most likely outcome resulting from anything but an overwhelming number of people showing up at the same time would be violence of some kin...

Hey, you don't need to sell me on the notion that police are corrupt.

Like I said, probably stupid. Gauges? I don't gotta use no stinkin' gauges! Tap and die man here, winging it on a tiny old TAIG. So far, so good, no baffle strikes (knock wood) and everything I shoot is politely quiet.

Being a guy who's never made a taper mount, but can appreciate the challenge of achieving concentricity with such a short part, I'd make the tube first, threading both ends. Then make the front cap and install that. Only then would I make the rear cap, turning OD then outside threads to fit the tube...

Re: Baffles or ???

Yeah, problem with really thin material is that it hits critically high temperature very quickly. So if what you're using it on tends to heat up a normal commercial suppressor quickly, it will likely bien through some sort of swarf packing in no time at all. Ultimate example - the finest grade steel...

Re: Baffles or ???

From what you're describing, it seems unlikely you have any experience with a suppressor. The pressure involved even with something as weak as subsonic .22lr is likely to pull a structure like that apart in short order.

The lathe swarf you're describing sounds basically like a coarser version of pot scrubbing material, the Chore Boy such as Dr Dater used to wrap around the reflex/ported area of the barrel on his integrally suppressed Ruger Mk pistol.

Re: More Chinacore.

If it were an aluminum core it might be worth a few dB to spend some time with a Dremel or other tool to hollow out most of those voids, opening out more air volume. But with stainless... that would be a lot of work. Probably burn through a few Dremel tool motors getting the one job done. But hey, i...

Re: First Form1 - .22lr

Bit of an aside, bit partially relevant. A couple of years ago I made a .22lr can with 1.375" OD 6061 tubing, 0.65" wall, and 3 x 60 degree single-clipped cones, with an OAL of about 9" and internal contained volume length of 8". What I was after was testing what maximum volume with minimal baffles ...

Re: Beretta M71-my first threaded barreled firearm-what now..

Enough larger that you don't get baffle strikes but not so large that suppression isn't great. And even without impacting the baffles, surface effects are a thing. With a 1/4" hole accuracy can suffer due to pressure feeding back from baffles, depending on baffle shape and proximity of the bullet. B...

Re: Beretta M71-my first threaded barreled firearm-what now..

Not much appreciable difference in noise reduction between a bore of 0.25" and 0.28" for .22lr subsonics. At 0.25" your alignment had better be perfect, or accuracy will likely suffer and you may easily get baffle strikes. 0.30" is still probably pretty good, but at about 0.32" bore I start hearing ...

No advice based on experience, no. But if it were me wanting a can for a CMMG Banshee, I'd go with the round can, as the offset-axis rectangular can would look odd.

Re: Brand new to silencers, some intro questions

That's right. A decoupling device is only for use on reciprocating barrels. The Banshee appears to have a fixed barrel (can't see why it would need to move) so a piston is not necessary, and may even cause problems.

Seems more of an OCD thing, those tabs and matching cuts for maintaining alignment. Of course who wouldn't want them if they were easy? Seems to offer a bit of a professional touch. I've just not heard any difference in orientations, good baffles seem vastly more important.
