Re: Double check resources... 458 socom form 1

I think 1.5 x 9 is going to be a bit small. The Bowers Vers 458 is 1.75 x 11.25. That's >150% larger internal volume. As far as pressures, I wouldn't be too worried. I think the 458 chamber Pmax is something like 35k. That's nothing. Coupled with a large chamber and bore volume, your muzzle pressure...

Re: Suppressor can without tax stamp

There are sites that sell components called "solvent traps". You can buy these, to form 1, and design your own stack.

Surefire isn't selling you a tube. Not only would it be illegal, but it's part of a proprietary system.

Re: 300 Black Out Welded Can

304 and 316 always want to warp. You need to either design around it or compensate with weld fixtures and setups. If need be, I'll attach large Al blocks near the weld, to absorb heat. I always do a couple test pieces to ensure I have the setting correct. The fixture works perfectly. It took a coupl...

Re: 300 Black Out Welded Can

I do have a question for T-Rex that I think will also help the OP. How much did your 5.56 can move after welding? Did you have any noticeable distortion using your DIY positioner? Any lessons learned that you can share on the welding? While I'm sure the parts had some final settling, it was nothing...

Re: Turning 17-4 (A)

I got the best chips from interior profiling and an, IIRC, SCLR insert. For the exterior, I do believe I have CNMG.

Re: Turning 17-4 (A)

My SB 9A is from, IIRC, 1947. I was able to use carbide tooling and take quite generous cuts. It's a nice metal to work with, especially for being stainless.

Re: 300 Blackout SBR

Since length trumps all, why not use a shorter barrel and reap the reward of fitting a longer suppressor? The 300blk was meant to run a pistol gas system w/ a shorter barrel. An 8" bbl, with an 8" suppressor, would net a <carbine length gun.

Re: 300 Black Out Welded Can

ECCO is correct that the baffle porting adds Mfr time. Being a home maker, I'm not too concerned w/ it. In reality, it added about 4min/baffle, to the entire process. I can say, however, it showed a noticeable drop in back-pressure, when compared to similar suppressors, w/o that feature. Typical 5.5...

Are you sure about this? Buddy of mine is test shooter for PPU and he is shooting them all the time from integrally suppressed MP5s. There's only a problem if you try to use lightweight subsonic bullets (less than 140 grains) Lighter bullets (we're talking 9mm projectiles, here) travel at a greater...

Re: 300 Black Out Welded Can

try giving your baffles a little more shoulder before the cone starts. Make that shoulder .060" thick, then cut the register .030" into that shoulder for the full .040" deep cone walls. Much less risk of burning away your skirt while trying to get enough heat into the distal cone for fusion. Yup. T...

Re: Integral Suppressed Sten Form 1 Idea

I just gave you a long reply and the forum ate it. Here's a brief review: 1. Full Auto silencers have been made from 100% Aluminum for over 50 years. 2. Porting negates the need for a blast baffle. 3. Almost all, full size, 9mm silencers, made form a large Mfr, are going to have 8-12 baffles. Why? B...

It is basically the same as a reflex galvanized steel sheet would certainly not be afraid, there is a life much higher than aluminum, rather comparable to stainless steel.

Re: .223 suppressor-comments on the proposal

As 40 said, not a reflex.
You don't need 50mm, 38 is fine.
Galvanized won't last long. SS or Ti
Galvanized also won't kill anyone.

Re: What to do with Diversified Machine new cone type for 22lr kit?

OP, the meter you're using is incorrect and very far from the capabilities needed. If you were actually getting 80dB, you'd have the next generation silencer. Hell, anything below 110 would make you The Man, especially from a semi pistol. There are only 3 meters capable (that reach the min Std) of r...

I don't always clip the first (centerfire rifle), but I always do the last. Seriously consider Aluminum parts (SS or Ti for blast or first 2) It will drop both your weight and final cost.

Asymmetrical should work great. I use a cutter equal to half the bore diameter and cut 100%, if not more, of the cutter diameter. Symmetrically clip the blast baffle or don't clip at all. So, what are you going to do about parts? I think I read that SDTA will cut you a tube at any length you want. W...

Re: What to do with Diversified Machine new cone type for 22lr kit?

I'm not sure what DM was thinking, with regard to those baffles.
They look like Rusty's RSC, with the flat tab from a Surefire Ryder and w/o the Ryder's vented mid washer.

You could cut the entire top off and almost have an RSC.
I'd prefer 10 normal cones to 6 of those.
