I shoot 7/8 oz. 9's in my 20 Citori over/under almost exclusively and virtually never lose a bird and rarely ring a neck. I watch many around me shooting 12 gauge 8's, ragging birds and twisting lots of heads. I usually choke modified in one barrel, improved in the other.

Exceptions tothis occur when it's windy, I'll go to 8's and if it's open big field shooting like winter doves, I'll choke full in one barrel, modified in the other.

9's simply smoke 'em.
