I recently bought a new SBE II , 12 ga, with 24" barrell and had shot it a few times at quail using IC choke and did not seem to hit very good but never patterned it. Then, as turkey season was to start I started patterning it with their full choke tube. I was amazed when I was hardly on the turkey poster . All of my hits were very high , most off the paper , all at about 35 yards. I used 3 different kind of winchester shells( all # 5's) including 3" magnum lead, 3" supreme extended range, and 3 1/2 " supreme elite extended range. The first thing I did was put in the C shim to increase the drop. No significant change in results however. Anyone faced this problem and got any ideas on how to fix the problem ? I also have a M1 benelli that shot the turkeys target head almost off under the same shooting conditions and tests.
