I recently was shooting my 300 wm with a Khantrol muzzle brake (which I think is made of aluminum) and noticed my accuracy was flying off unpredictably. I took a look with my borecam and noticed the rings between baffle are badly pitted/eroded, I'd say it's had easily 1000 rds through it over the years.

My question is--is this something that can significantly affect consistency (I assume it must be messing up the gas flow and hence the bullet trajectory)?

If so, is it worth my while trying to grind it down to even it out, or should I call it a day and get a new brake?
