How effective would this design be?

Hey guys, new to this forum but I frequent SD&F1... started playing around with Fusion360 tonight and made this 60° cone... How well do you think a design like this would suppress in say a pistol/rifle? (one in photo was designed for .45)

any input is appreciated

Not well. There is no turbulence created and stagnation would be low.
You need to make the gas swirl to get good performance. And then trap it in a pocket until the borejet subsides. Otherwise it only allows gas to expand, but still rushs out quickly and under high force(rate) even though pressure has dropped.

It was late last night, forgot to add it would be clipped (I suck at fusion 360).... could the design work if were modified?

Would you explain the detail at the entrance to the baffle.

Yes, the design has some potential, difficult to machine for most Form1 builds though.

With a scoop/clip(whatever people call them this week) it will help notably.

I was just curious since I have never seen the design, finding there is only so much you can do without live tooling..

I was all thinking beside doing the clip to possibly turn the flats on the side of the cone to 60s. so it would be a small cone on top of a larger one essentially. then in theory the gas would be trapped by the back flats on the smaller one.

This reminds me a lot of a Huntertown Kestrel baffle and I have upgraded a bunch of those because they didn't work. The face groove you have drawn into it might change things quite a bit but I couldn't imagine trying to machine that little groove with a face groover into high temp alloys. Sometimes you just have to build things to see if they work, I have had quite a few ideas that looked good on paper but when put into action failed.

Give it a try. A lot of folks here told me my 300blk design wouldn't work well. Turns out it's Hollywood quiet with subsonic 208gr AMAX.

Did you ever make any changes/add features, or keep your can as you presented it?
I remember you saying there's a lot of FRP.
Wondering if you ever tamed it down?

I pressed a 60* cone into the sleeve that was the blast chamber. It's about 3/4" away from the muzzle. It really helped the FRP.
