I've read this article numerous times that Gil and Vicki Ash wrote, and still can't believe a Mod. choke can hold a 25" killing pattern from 25 to 45 yards. I've never patterned a Mod. past 35 yards. They say:
"Modified may well be the single most useful all-around choke of them all. Obviously, those crafty trap shooters were on to something."
Well, I'm not a crafty trap shooter, so I decided to try some patterns with a Mod. choke at 25 and 45 yards, and see what I get. I personally don't know anyone that uses a Mod. choke for handicap, maybe some do. They never said the velocity of their shells, so I'm going to use 1200 fps. 7-1/2's.
It appears this test is flawed to the point that there is no idication of what load was being used ie. what type of shot, what type of load or velocity. Additionally, the different manufacture of chokes should be considered also. Does Briley have a better patterning choke than a Carlson or Wright?
