Re: Baffle orientation

what effect does baffle spacing have on higher port pressures? Closer spacing raises port pressure. Previous ports allow more gas pressure on the next port inline. Wide spacing lowers downstream pressures due to cooling and expansion. Think about this : normal practice is ported cone baffles with a...

Baffle orientation

Its often asked if ports should be aligned. Yes ported cone and K baffle should. The reason is asymmetric port flow reinforcement in a reducing pressure environment. Each baffle in turn strips high pressure gas where the port or clip allows a stream of gas to move forward adding to higher pressure p...

Re: Stagger-sway suppressor

I have never made a investment in the finer details of the Nielsen but can make a working model. First keep in mind the bullet has left the suppressor before the suppressor body is pushed away from the pistol. The piston keeps the suppressor body centered having contact points front and rear. The pi...

Re: Subsonic 45-70 from 10mm rated 45 pistol can

45 acp 410 grain @ ~ 750fps out of a 5-inch barrel. That will put some swing in your dingaling. There are powder burn differences between rifle vs pistol power and you will have to deal with a higher volume powder in the short .45 acp suppressor plus possible threading issues, but it might work wel...

Re: .22 LR barrel porting.

I would start with the smallest size until you reach your desired speed. Nobody can give you an exact size as chambers very as do barrels. The old saying of the devil is in the details apply. Make sure you do not cut into the chamber or the lands center it in the throat.

Well what did you do. For a integral turning barrel on center is a option.

Not true integral since the barrel won't be ported. But the tube will mimic the look of a bull barrel. Anyway, I'm mounting the receiver and barrel in a Viper fixture so I can thread the barrel. I keep fighting myself mixing up inboard and outboard screws while adjusting. Just taking a break and ha...

Hey guy nice to see you post. I know your work is above reproach so lets cut to the chase. The chances are the bore passage is to tight. Open up the muzzle cap and if that dose not work the baffles are next.

Re: .300BO Keyholing With Different Sized Cans

If both of these suppressors perform without problem on other guns then the problem is the rifle. A minor misalignment of the mounting is the cause. Only a baffle strike or a near one will cause these issues.
