I have a 33xc chambered barrel in which I shoot 300 grain bergers at 3100 fps. Just installed a new brake. It is at an angle of 20%. To time it, I will have to use a washer. However I wonder, how important it is to time a muzzle brake perfectly? Does it impact percision, ES/SD something etc? If it is not going to have a big impact on precision and SDs, then I would like to avoid the labor .... looking for inputs from those with experience/view on this....
