Anyone have a cool trick for verifying the freebore on a newly cut chamber, vs. the freebore from the reamer spec? Like, my reamer says ".170" and I want to verify that that is actually what it is cutting. What I thought of doing is reaming a small gage with the reamer. According to the print, the freebore is .170" long x .3083" in diameter. My thinking is that I could turn a piece of drill rod or something to .3082", and it should insert into the gage no more than .170" if the freebore is correct. Maybe there's a simpler way.
