I'm gonna shoot mine as soon as my mag blends arrive and we get a nice day. I bought the I.C. .690. Boy I wish their was a way you could rent a couple chokes and try them out in your gun with different shells. Maybe 6 different sizes. For example a .710, .700, .695, .690, .685, .680. Pick 2 loads . Mag Blends through the .710- .690, and Hevi #6's 0r 7's through the .685 and .680. Pick the best patterning choke in your gun , it and send them back so someone else can try 'em.Then buy the one that shot the best in your gun. Also the ammo companies could sell a pattern test package . Say a 5 shell box 1 mag blend 5x6x7 , 1 Blend 6x7, 1 HV #5 ,1 HV #6, 1 HV #7, 5 patterning targets That way you could buy a good choke and know which size shot or blend shoots best without breaking the bank. Then you could by a 25 box of the best shell. Just a thought.
