I bought one of the Numrich Savage 300wm threaded barrels
& a brake from Ross Schuler
I proceeded to remove metal a little at a time from the brake reinstalling & measuring progress
-reinstalling & measuring progress - reinstalling & measuring progress -reinstalling & measuring progress

the last little bit was just a little bit to much................now what ?????
so now I'm faced with the choice of going around another complete revolotion or make a shim
so I made a ship from a diet coke can....... whats the chances of exact thickness for needed timing ?
it lined up perfect ........
so now my question is how will aluminum & Stainless do together in this application
I worked as a auto tech for 30+ years & know aluminum blocks & steel bolts equal white rust that is exstremely hard to deal with
I see no need to remove brake untill barrell is shot out - then I could sacrifice the barrel if need be to remove
as long as there isnt something I dont know about this paticular application
thats why Im asking the pros & barrel nuts
