I had a few questions on the cylinder/full chokes mentioned in the letter. When I measured them I got cylinder and .019" restriction which I thought would be modified? As well it lists 100 pellets in the cylinder and 160 pellets in the choked barrel in a 30" circle at 40 yards with #7 shot. Was Parker using the British #7 description for what North Americans now call #7.5? From looking at photos of hang tags Parker used 7/8 oz for their choke testing on the 20 gauge. Did they use 1 oz for the 16? If 1 oz of 7.5 that would be 350 pellets. 160 out of 350 would be about 46%. Am I off the the choke designation? Thanks. Just trying to learn here.
