Re: 300 BLK design

heres the most updated design based on all your advice im going to clip and port the cones, i just didnt show it in the drawing. i went with spacer diameter as large as possible because i think that design would work best on my .270 as well as working very well on 300 blackout http://i1175.photobuc...

Re: 300 BLK design

It's all relative. You space the first few baffles well enough that the gases can expand in them properly, and then you gradually increase that spacing even more have you tested this? i understand your theory behind it but im not 100% sold that increasing spacing would be better than decreasing or ...

Re: 300 BLK design

But, one must consider that gas jets traveling supersonic unpon leaving the barrel will enter Choked Flow conditions and must drop velocity b/f they can spread to fill the OD properly. So, if not enough linear distance b/t baffles, the core of jet will pass through into the next chamber w/o properl...

Re: 300 BLK design

Ported spacers that are smaller than the suppressor ID offer improved gas delay while also optimizing volume and reducing weight. Spacing is also critical. Note that the gases lose pressure in every subsequent chamber, so that for a given longitudinal distance, a gas particle will travel a lesser d...

Re: 300 BLK design

Many different variables influence cone angle. Caliber, projectile velocity, pressure, etc. While I can't tell you exactly what's optimal, cones within this interval of angles have given me, and others, good results. Also, don't forget variable- angle cones, also known as swept cones. You'll notice ...

Re: 300 BLK design

What Bender said. Mixed baffles don't offer much benefit, and they complicate manufacture. Between 45deg. and 60deg. clipped cones should get you in the sweet spot. Ported spacers that are smaller than the suppressor ID offer improved gas delay while also optimizing volume and reducing weight. Spaci...

Re: reason for commercial cans to be same outside diameter?

It is best to design for manufacturability and use materials that are stocked by suppliers. I wish the US would go metric. Burma, Liberia, and the US are the only countries not using it.

After shortening it to 1/4" total length, don't make it hollow. Make it solid, then cut a scoop all around. Instant half baffle.

Re: Titanium 22LR K-Baffle Build

Those endcaps are way too long. At most, 3/16 of threaded engagement surface suffices. That's almost a whole inch you can lose from the can, or increase your baffle count. Also, I would suggest modifying the front endcap to have a cone shape or at least a scoop. It will dramatically boost performance.

Thank you very much for the response, that is helpful.

Re: Squeaky, high-pitched-sounding silencers

I've managed to get a somewhat Hollywood-esque high pitched sound on exactly one suppressor only, and that was a mini-can that I built for a Beretta 21A. 4" long by 7/8" OD, with 3 parabolic baffles, all welded into a monocore, CF tube.

I didn't spot this while following the thread but perhaps missed it, so my apologies if that's the case.
