I have a couple of guys with FTR barrels that share a reamer that they keep with me. Very boring team reamer .168 freebore etc.
One of the guys switched to a new brand of barrel (still one of the big 3). I send him home, he calls: "Hey, the freebore in this thing is like 70 thou shorter than before, what gives?"
Other than a barrel with a much tighter bore diameter than he's used to from the other manufacturer... What could cause this? The reamer did other barrels at the same time, never left the reamer holder, those barrels are fine.
I know bore size can change effective freebore... but 70 thou shorter seems like a lot.
