The reamer appears to just fixes the leade. That's the problem area according to Ned's experience with various manufacturers that aren't named Colt. Based on my chrono testing, I could really probably use this on a few of my non-Colt barrels. My 2 Colt barrels did indeed show the slowest velocities which now makes sense.
