what's the bore dia on the PWS FSC 30 muzzle brake? I am wanting to possibly use one of these 30 caliber brakes for a .338 federal build and I am curious if the bore dia will be large enough to pass a .338 dia bullet. If someone could mic theirs and tell me what it comes out to that would be great. If it is too small which I'm doubting it shouldn't be too big of a project to drill it out to .350

I cant find my calipers but a .308 bullet has about .03 of clearance from checking by hand. I think you should plan on opening up the hole, you never know how true it is to the threads

I measured mine just now at .368.  It could be a couple hundredths larger.
