I have found out that when shooting 00 buck, that a full choke deforms the pellets and creates a quicker spread. Since then, I have changed to an IC choke which is the best "all purpose" choke for my needs (skeet, upland, 00 buck and slugs). However, I need to be able to shoot coyotes out to 70 yards. From what I have read, #4 is one a the best options for handling coyotes (I don't have the money to spend on the Dead Coyote load). Does the same deformation effect take place with #4 buckshot through a full choke or should I stick with the IC choke?
