I have bored a bunch of brakes, ready to be mounted on your rifle.

I currently have 7mm (Bored to 0.314), 30 Cal (Bored to 0.338) and 325 Cal (Bored to 0.345). I am still set up to bore more calibre, any caliber desired let me know I will bore them out.

I make a threaded stub on the lathe and leave it in there until I am done. If I have to remove it, I make a new one. This way it is always concentric. I pre-bore with a drill and bore to caliber using a boring bar. 0.030" is a bit bigger than I would normally do if I was installing a brake, but it will account for any misalignment on your rifle threading.
