Re: .22 LR barrel porting.

Freebore the barrel back to 3.75” and it will make all ammo subsonic then drill ports as you like in the freebored section to let out gas

Re: 22 freeze/expansion plug suppressor

Been a while since I was last on here. The old 5.56 can is getting some age on it. Has not been getting used as much as it did in the past. Ammo prices are to blame for that. Been having some rusting issues with it. It had been left in the safe for Covid time and when I got it out it had a nice coat...

Only had 2 mags so it was shoot and reload. was an all day event and this can was used at different periods of the da...

I did a reflex integral so the barrel is in the blast chamber and...

Hi Sub-sonic I am about to do a home build for use on a ruger bolt action in 300 blackout, subsonic ammo only. I have some 2" SS tube and have found the correct size freeze plugs for it. I was intending to follow the build you did for the 308 suppressor but then I thought the 300 blackout is o...

you are thinking opposite to me. I am thinking no pressure signs and still room in the case add more powder

IMR4227 supersonic BLK

so I am loading 130 grain bullets in the BLK and I have lots of 4227. I searched for load data and get conflicting information. IMR site says start load is 18 and max is 19.2 so I load up 18.5 and go see what happens and its a good load. primers look good and all is ok. velocity is 1945fps from a 10...

Re: Porting a barrel for a reflex design?

personally I dont like drilling into the bore/rifling. I think its better to counter bore the barrel to make it a smooth bore in the area to be ported. drilling ports is a smiple matter of using a sharp drill and steady pressure. dont force the drill. then use an end mill thats larger than the drill...

Re: Improvement suggestions for this monocore?

Well that would be silly. If you're chucking the monocore, why fill the tube with crappy washers? K baffles well designed and executed will deliver much more efficient suppression than any monocore, and certainly better than any freeze plugs. flat washers spaced 3/8" apart would do far better ...

Re: Sound suppression w/ direct thread vs threaded muzzle brake

if you use a decent brake that directs the gas sideways into the expansion chamber on a reflex style can you will get some benefit. like this one

but if you use some pseudo wanabe brake then well you are waisting your time.
