Muzzle Break Help Pinning

[Wilson Combat Rules]

Muzzle break help I need help knowing what kind of drill bit to use. I have tried everything I can think of it doesn't touch it. Don't even get started is there a special kind I need to get or do I have a muzzle break that can't be drilled.

if carbide or cobalt won't cut it then you may have one too hard

never seen one that couldn't be drilled with a solid carbide twist drill but if you have that one of a kind.... take it into a good machine shop and have them sink it with edm machine.
