300blk blast chamber size (I searched)

Hello again. After my successful 300blk can I made for my AR15 I want to make another for my Ruger bolt gun. This time around I think I'm going to "cheat" and use a pre-made tube and cups. From the options that are out there I see the first "cup" is very close to the muzzle. I could make a simple sp...

Re: New lathe purchase, is this enough?

That's about the size of my Grizzly lathe. I've made 3 suppressor and 10,000 other things with it. Best piece of equipment I've bought in a while

Re: How effective would this design be?

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?...

Yes. Just like that. But I'm dealing with an 18" barrel so i think I would need much less than 4x 5mm holes.

Slowing down "standard velocity" 22LR

I once read that there was a feature designed into an integral pistol that slowed down standard velocity 22 to subsonic levels. I think there was a port drilled in the barrel that bled pressure off into the tube. I don't remember the port size but I think it was 1.250" from the bolt face. I have a v...

Re: 45 ACP K baffle help

I don't have a mill. Only a drill press. I'm going to make a 45* angle jig that I can mount my 4-jaw chuck to then bolt the whole thing to the press.

What is your method or process?

45 ACP K baffle help

I did a search here (using Google) and didn't come up with anything. What diameter end mill is best for the mouse holes on a 45ACP K baffle? I found that a .500" bore is commonly used for 45.

Re: cutting threads question

I do this Tube ID + .01 (.005 a side) + 2(.868 * TPI) = Cap OD. I skim (bore) the ID .005, a side, to make baffle entry a bit easier. Example: 1.5" x .065 Tubing 1.5-.065-.065=1.37ID 1.37 + .01 + 2(.868 * 1/24) = 1.452 for OD of Cap If you do it this way, you can make ONE cap first. Use this as you...

I got out to the range today. I have a friend with an 300BLK AR pistol and a brand new 30cal Saker. We shot quite a few times side by side as a yard-stick to my F1 build. Mine has a hell of an FRP but quickly quiets down. Have a look....

Thanks for your input CMV. At the end you mentioned a 60* chamfer. Im guessing that you suggest I make 60* cones and nest them into this chamfer? Sorry I sound so green.

Re: 300BLK M-baffle build

I wasn't sure about clipping. No big deal to go back and add later.

Do cone baffles work better for this application? If it's too loud I suppose I could add cones too. Would aluminum cones work? Or would I need to use 316?

Thanks for all your input!
