Re: How did I do? (baffle design)

Can you point me to a study showing Aguila SSS keyholing or even being less accurate than bulk ammo? The tests I have watched all show reasonable accuracy and round holes even out past 100 yards. Mostly with 1:16" twist. I do understand they recommend something like a 22" barrel to give it plenty o...

Re: budget suppressor for short barrel 300blk

If you're not able to machine a cone to fit into the end cap, then sure, leave the somewhat longer space between the last baffle and that conical end cap. The smaller exit hole matching those in the baffles will help in noise reduction. The first end cap with the much larger hole may as well not be ...

Re: budget suppressor for short barrel 300blk

Stuff another cone in that endcap, with a bit of a longer skirt on it to keep it halfway between the previous cone and the exit hole, or with a step cut into the endcap to retain it. Make the exit hole in the cap a bit smaller. Those will get you a little bit quieter. Looks a bit short to me for rea...

Re: Would like help making K baffles

If you do decide to go with K baffles (allowing that ECCO is undoubtedly correct), taking an hour or more to poke around at the links in the completed build thread will be an education. Especially the last pages of the thread, as a lot of the earlier images have been lost due to various image hostin...

Re: Not enough barrel!!!!

I'm curious how the crown gets finished when counter-boring for an adapter like this, or even more so when something like a 10-22 bull barrel gets used as a short barrel with integrally machined suppressor as we've seen displayed a couple of times on these forums. Seems getting the finish just right...

ECCO Machine on Facebook is one, but that's getting a bit serious, more of a recore type of guy as his baffles are state of the art. https://www.facebook.com/ECCOmachine/ I mean, your baffles no doubt quiet things somewhat.

Re: assembling a suppressor

First of all, if you don't have the know-how and manual skills to turn those into finished K baffles, find someone who does and pay them to do it. Your suppressor will significantly improve in performance. I see waist ports, but no face scoop opposite those vents to push pressure across the bore and...

Re: B&T VP9 Welrod 9mm Silenced Pistol

Indeed, Stan1's pair of replicas (one for display, one a working unit in better steels) is very impressive. His videos letting us hear it in action seem very impressive, both for suppression efficiency and accurate shooting. Seems it metered at just under 124dB, with .32ACP. https://www.dropbox.com/...

I wouldn't quite class it as pretty darn good.

Yeah, my experience with copper mesh some years back was similar. Didn't seem to make a difference in noise level, and cleaning it was just nasty. Ended up tossing it instead, unravelling a new scrubbing pad and twisting and wrapping that. Several cycles, maybe 150 rounds of .22lr each time, before ...

Finally committed to porting a 9mm barrel today to scrub a bit of borderline transonic velocity off my 147gr of choice. Winchester JHP were averaging 1,100fps out of a 9" barrel but the odd one was going to the mid-1,120's, coming close to not sounding good and flirting with the accuracy issues inhe...

I have one competition type air pistol which offers only about 1mm clearance between the air cylinder and the barrel, so not much clearance for a tube, and if it was to be suppressed for use on rats (avoiding disturbing neighbours at night) this would require an asymmetrical solution.

Re: Selecting baffles for a F1 build

With your given parts I'd turn a bunch of spacers to make up the difference. Use thicker walled aluminum tube to match your tube's ID more closely and cut recesses for the baffles fore and aft. About 1/8" or a bit longer, T shaped cross section. A bit fussy to assemble but it would be stable, and al...

The benefit will vary depending upon the calibre and the pressures involved.
