Re: New CCI Quiet-22 LR - 710 fps
Yeah, likely measured using a smartphone mic and SPL app. Even the dirt cheap Chinese SPL meters rate unsuppressed CCI Quiet around 120dB, decently suppressed from a pistol at around 102dB. My smartphone has a fairly decent microphone for a phone (Samsung Note 3) and gives a suppressed reading of ab...

Re: Maglite
I've used a tap and die for making my last couple of rimfire suppressors. Not fun, and more crooked threads than straight at first, but I'm learning to get it right with practice. Having an over the barrel portion about 3/4" beyond the threaded portion helps with maintaining alignment provided ...

Re: How to make buckmark quieter
From what I have seen published, it seems the Sparrow uses a blast baffle bore diameter of 0.25", tapering larger towards the end cap which has a diameter of 0.27". Provided your barrel is precisely threaded such that the suppressor is perfectly concentric to the bore, the risk of a baffle...

Re: How to make buckmark quieter
Probably won't cycle the slide, but they'll be quiet alright. About like a beer can being popped open with a decent suppressor in place. Unfortunately, at least in my old pistol, they also don't tend to be very stable. Perhaps the Buckmark has a higher twist rate to the rifling? My Unique D4 with th...

Re: What guns do you own, and why?
A woman who is drawn inexorably towards more powerful guns is somewhat against the grain of stereotype, especially considering the popularity of silly video demonstrations of women 'failing' when handed shotguns and large calibre pistols. Good for you. If you find something you love to do, provided ...

Re: Changing the angle on a K-Baffle
My initial baffles for a .22lr pistol were very long, using about a 45 degree angle for the cones. These were rather inefficient. It took quite a long suppressor to get half decent suppression with these somewhat primitive K baffles. Since then I've shortened them, to the point where they now use a ...

Re: smooth bore pen gun - 25 acp
Here's the finished pen gun, blued this evening with Outers Gun Blue. Came out more brown than I was expecting, which is good as I'd hoped for a brown just expected more of a cold grey-blue. Before doing that I was concerned about the firing pin strike area at the breech, as when dry firing without ...

Re: smooth bore pen gun - 25 acp
This project of yours, BCJ, it stuck in my head. Couldn't shake it. And so, you know the thing about idle hands... I've gone ahead and done a bit of experimenting. My first prototype was based on a 6" length of airgun barrel in .22", bored out to be a slightly sloppy fit for .22lr. I press...

Re: integrally suppressed old French .22LR pistol
Ah yes, and one more point with a question. As usual after a couple of dozen shots I took the suppressor apart just now and cleaned the baffles. Inspecting them I see that, as usual, the distribution of dirty lithium grease is fairly even on the faces and the insides of the cones. Also as usual I no...

Re: integrally suppressed old French .22LR pistol
Well that fleshes out the similarities quite well, thank you. I did make a slightly taller rear sight blade, actually a bit too tall at first and I've twice filed it down and now have a semi-circular notch cut which helps a bit in using the soldered on brass front blade at various ranges. I turned t...

A few searches have netted me nothing like my little pistol... it would seem I lack the 'Google-fu.' Perhaps you have an image of such a French special operations pistol?

Re: integrally suppressed old French .22LR pistol
Well I gave up. The 7" ported barrel with integral suppressor was quiet to be sure, but accuracy was sometimes off. Just could not group consistently for long strings. So I concluded that the very slight off-centre bore was just too big a problem to overcome with shimming of the muzzle plug. I ...

Re: .22 shorts with a suppressor, any advice?
While I haven't tried the 60g Aguila, I have found that I get a slight graze with most shots when using CCI Quiet through the ported 7.5" barrel of my .22" pistol. Never a trace of it with faster ammunition such as Remington subsonic or CCI SV. Those and other projectiles leaving the muzzl...

Re: The Hush Hole?
Hm. Some sort of acoustical destructive interference causing the bullet to vibrate perhaps? Shapes contribute in often startling ways to the behaviour of sound, and since you're saying a parabolic baffle behaves differently (better, from a suppressor builder's perspective) than other baffle shapes, ...

Thank you very much for the response, that is helpful. It seems that from your experience with your very flexibly designed rimfire suppressor that while certainly an interesting phenomenon, the Hush hole in the middle of the baffle stack is not a definitive, or 'must have' solution. Even if it is be...

Re: Another Review/critique request. 9mm boosted can.
There is a limit to the 'more is better' approach with K baffles. In my tinkering I found that long K baffles with sort-of-okay porting (I was learning, still am of course) in a very long can (about 11" OAL with 3.5" over-the-barrel, the barrel ported) made for adequate but not stellar noi...

Re: Bore size for 9mm cans?
I've found 0.25" quite satisfactory for .22"LR, provided alignment is pretty well perfect. My suppressor length has settled on about 3.5" ahead of the muzzle and as much behind, plus end caps for an 8" total length, with ported barrel on the pistol. The bore is true to the barrel...
