Re: Muzzel brake errors
Opinionated Chad here. Get your salt. . .
I call bullchit on harmonics.
If I'm wrong then there's a simple solution. Change the load. It should/will improve.
I've installed hundreds of brakes. Some work, some work better.
Radial and symmetrical ports seem to work the best.
Brakes with holes on top/sides should be avoided IMO.
Case in point. In 93 the AMU went to the M-16 and they cleaned house at Perry. Tore the Marines a new one that year.
Following year PWS built M-16s fitted with compensators. Guns were fine on the short course but had elevation at 600.
Why?
Look at a comp and its pretty obvious. Ports on top/sides. It induces a yaw on the ass of the bullet upon exit of the crown.
2004-2005: I was part of the design team for the Dakota Arms Scimitar built for the Jordanian military. 308 and 338LM mag fed bolt guns for use againts militant Islamists.
My boss made a brake with non symmetrical ports against my recommendation. Guess what? History repeated itself. I made a symmetrical brake of same length/weight as his.
Groups improved even more~likely due to the gun being easier on the chooter.
Experience from 20+ years at this (in one capacity or another) tells me its NOT due to fancy words that get used way too much on gun forums.
Opinion over. Light your torches and fire the ovens.
Happy Saturday Germs.

PS:
If it were me id first ensure the brake is tight. Assuming it doesn't have non symmtrical ports I would pull the stick, indicate the bore in the lathe, install the brake and check TIR. It should be zero. If its not then bore the id till it is.
If it is be sure to check TIR in two places to ensure its on the same vector as the bore. If its not, bore till it is.
Leave the drills in the tool chest. Single point boring bars are what you want as they cut a clean hole on spindle center. Drills just make holes w/runout bigger.
If this still doesn't work, sacrafice a puppy and make a deal with the devil cause your just screwed.
Kidding on the last part. Use a cat!
