barrel torque

Thinking further about the brake,... If the ports were jetted in the opposite direction maybe then?

I can't see a brake working like that. It seems that the gas would just escape at what ever port it has the chance to get out of first.
Something about mass and inertia, or the lack of, I think. I do like Harrell's brakes though.
I hope they don't spin them selves off. ;D

Seems like my switch barrels require more effort to get off after they're shot. Maybe I'm more tired or something. ???

Actually your statement about requiring more effort to get off makes sense considering all of the above and if your rifle has a right twist.

They did appear to be that way to me but I have zero experience with rifles with muzzle brakes. I assume there never is rifling in a brake that is added to the barrel after manufacture. If that is true then it is the direction of the ports that would counter the torque.(to some degree)
The post by CATSHOOTER and the Colt's problem got me thinking.

I believe it's just the drill pattern in the opposite direction. The holes point straight out. I'm thinking that the forces involved here would require the the ports to be angled or pointing in a direction other than 90 deg. from bore.

I could be wrong, Jim

I agree with you....it makes sense

Harrell's calls that pictured brake "Counter Torque". But maybe that is just a name. The holes do all come straight out as you can push a bore brush thru the brake from one side to the other.

Even though the pattern is spiral, if the holes are straight, then there is no twisting force.
