I'm looking into Form-1'ing and building a dedicated Grendel suppressor because the threads on my AA uppers are not standard and I want a direct thread. I see a lot of people happy with a .30 cal can with a standard industry overbore of 0.067". I assume this is for convenience. Is it worth it to keep a tight overbore? I have read mixed comments. Some people say keep a 0.05" overbore, some say 0.06" and some say as tight a 0.04". What say the Grendel community? I understand this is a risk vs reward, but some say go larger for safety as the audible difference is not noticeable, and some say tighten it up as long as you have concentric threads, but not too tight to get a baffle strike.
I just want to build the best all around suppressor specific to my Grendel's since they all share a unique thread pattern. Assuming a perfect world, what would you do for bore size. I will add in a safety factor of my own, but what would be ideal in your opinion as a baseline?
