Larry, My original unaltered 28-ga. Repro chokes, carefully miked by a professional using a professional bore gauge is as follows:
Q1/Q2 = .004/.008
IC/M = .006/.016
M/F = .014/.034
We all know that actual constriction doesn't tell the whole story, you have to actually do some empirical pattern testing with various loads to determine what kind of patterns your particular gun shoots, right? In your post above you never admitted that you actually shot your M/F choked barrels to determine effectiveness. It would also seem that either:
a) The chokes on your guns were mismarked.
b) You used inferior equipment to measure the chokes.
-or-
c) Operator error in measuring the chokes.
...and since you weren't able to even get the gauge into the barrels to measure them, it leads us to come to only one conclusion.
