Interesting, my experience with Model 21's does not match up with eightbore's post. My 20 gauge 21 Skeet with two sets of barrels has skeet 1 and skeet 2 (in and out?) in the skeet barrels and measure tight on my non-micrometer measurement tool with the tighter barrel approaching modified. The other set of barrels which are marked M/F provide readings at tight modified and full. I wonder if these measurements are a result of the age of the gun (1948) thus the use of fiber wads? I anticipate that modern plastic wads may result in tighter or at least denser patterns.
My trap grade 21 12 gauge has barrels measure light full and full consistent with the markings on the barrels.
Thus I don't think these are anemic constrictions.
Schwings Model 21 book indicates that Skeet #1 has 87% of the pattern in a 30 inch circle at 20 yards and 33% at 40 yards. Skeet #2 is reported to have 93% of the pattern in a 30 inch circle at 20 yards and 50% at 40 yards. Skeet #2 is reported to provide the same shot distribution at 30 yards as the Skeet #1 at 20 yards.
After writing this I think one reason I miss the high going away shot in 5 stand is I am shooting the wrong barrel at that target.
