Pete, I saw your post on the Lefever forum and thought you and others might be interested in the profile of that right barrel choke. It starts a slow taper at 4" aft of the muzzle with 4 thou diameter reduction in the first two inches of run, then 4 thou in the next inch, and 6 thou in the last inch out to the muzzle. Total constriction is 14 points. That's with my Baker bore mike.
Some of this Lefever bore and choke technology still seems to be mysterious and that's why I'm particularly interested.
