I put my 12ga GHE skeet on paper tonight. It's bored .731 in both barrels, marked Skeet Out on the right barrel flat with .007 constriction and Skeet In on the left barrel flat with .004 constriction.
I shot 1 ounce of #8 with an actual count of 415 pellets. At 40 yards it put 173 pellets in a 30" circle for 41.7% from Skeet In (left barrel), and 177 pellets in a 30" circle for 42.6% from Skeet Out (right barrel).
What I learned tonight; the slight constriction of .004 and .007 delivered barely more than a cylinder pattern (40%), the Skeet In and Skeet Out markings add monetary value but each barrel is so close in performance as to not matter which is shot first by percent, BUT the Skeet Out had a more uniform pattern making it the better choice for a long shot, the gun will perform best on 25 to 30 yd targets, when shooting sporting clays if there is a long shot (30+ yds) I would do well to have a few 1 1/8 ounce loads in my vest to increase my pellet count and odds.
There is value to patterning a gun.
