This can be one of the worst things that can effect accuracy if a component is poorly attached
to the muzzle.
Believe it or not It it not that uncommon and besides effecting accuracy, it can also cause injury.
It was recently brought to my attention buy a friend and fellow gunsmith that there had been an incident where a bullet actually exited the side of a suppressor. This was purely a case of a poor installation, and could have been avoided.
Even when I do all of the machining on the brake, and thread the barrel in the lathe my self, I have one final check after installation. I use tools that I made just for the prevention of this problem. They are made of aluminum (So they don't damage the bore) and two to three inches fits the bore of the firearm the rest is machined to the required clearance of the brake or suppressor (Normally .020 thousandths larger than the bullet for clearance). If everything is perfectly aligned the tool will slip right in without any resistance.
This is a final check to verify that everything is perfectly aligned and there will be no bullet strike. Everyone can make a mistake, and this is just a way of making sure everything is good and safe. The fact that a suppressor is longer than most other attachments to the muzzle, this becomes even more critical.
There is speculation that a crush washer was the culprit, But with good thread fit, and proper installation, this should eliminate these problems. "BUT" a final mechanical check should verify that the installation is good and most of all safe.
Never assume that everything is OK, Prove it.
