Re: on form 1: 7.62 or 30 cal
I just put 30 cal on mine, but doesn't really matter. If you're diamond drag engraving, 30 cal is much easier stencils to trace

Re: What would cause inaccuracy when hot?
147gr ACME flat point bullets. They're coated cast. I can remove suppressor and immediately go back to good groups, so I think issue is in the can. Just weird. And can only tell it at 50 yds. Not bad enough to miss steel targets at 10-12 yds, smallest is 6" though so would take a lot to miss at that...

What would cause inaccuracy when hot?
My 9mm is Ti tube & endcaps, 7075 K's. I *thought* it has been good to go all this time....nice sound & just fine running on a Beretta 92 at typical pistol distances ....~10 yds. Got a CZ scorpion & it sounds great there too. But now I'm shooting at 50 yds & notice after about 10 shots my accy goes ...

Re: Teflon tape
Never tried but remember reading in the past it made a mess. Have you tried anti-seize on the barrel threads? I end up with issue that tightening down a direct thread suppressor, the encap wants to stick to the barrel threads more than the tube & instead of removing suppressor, it wants to disassemb...

You'd know that indicating it in 4-jaw. Gets down to almost no runout, move dial indicator back on piece a few inches and now there's runout. If no matter what there's runout when measuring a few inches apart your stock is out of round. If you have the needle type dial indicator vs the plunger type ...

Re: end cap strike, 9mm threaded can
I'd still find where the issue is. .060" is a safety margin, not min clearance to work. Even if baffles have same bore size and bullet clears everything, being so far off center thru the suppressor bore is likely to play hell with accy. Again....ask me how I know..... :) Maybe not every single insta...

Re: First Form 1 Build 6.5 CM
I'd do a P or 21/64 size. .060" over. That's just me, some would go tighter. There is very little gain going as tight as possible on bore size all else equal and 6.5CM is still going to be loud. I've never seen published subsonic load data for it but if you were planning to work down a light trailbo...

You said in a previous thread you're making a .308WIN can & using 17-4 internals. Aluminum of any sort should be 0% of that build. Any suitable material for your tube will not be marked with punch & hammer lettering. Recommend you find a shop local & have them do it. Even a trophy shop probably can....

Since I know about nothing, have 2 big questions for now. #1 1/8" or 3/32" 319L rod is what I think I should use. Endcap is 416 & tube is 316L stainless. #2 I'm not sure exactly how the we...

Re: First form-1. How much clearance for .22lr ?
I use 17/64", but am not drilling freeze plugs with a cordless drill. So depending on how uniform the FPs are, how well they fit the tube, how precisely you can measure center, how accurately you can drill center, etc should increase your fudge factor from that min diameter. I had accuracy issues wi...

Re: Machining cerakoted parts
For cerakote, what you are describing will work fine. I cerakote, then engrave often to make the engraving standout or be blackened for a neat look. The issue you will have is creating bad wear areas. While I really like cerakote my one major gripe with it - or a lot of finishes - is that it wears p...

Cmv, his spacing, clipping, and porting all seem to resemble the Sig silencers. Are they poor performers on 300Blk hosts?

Re: 300 Blk suppressor
What is baffle spacing? Those look WAY too close together for 30 cal. .600 - .700 neighborhood is a good place to be. .625 - .650 is good distance if 300BLK subs are your primary application. Why the tiny port in side of cone? Is that all cones or just first? Regardless, I don't think you want that ...
