I use 1 oz. of #6 nickel plated shot in my IC barrel at approximately 1328 fps and 1 1/8 oz. of # 5 1/2 nickel plated shot in my Mod barrel at approximately 1325 fps. Per Tom Armbruster, the pressures are 7440 psi. and 9620 psi. Velocities vary a little, but the above is close to an average. The #5 1/2 shot provides a little more down range energy with approximately the same shot count as the #6's. My pattern board indicates that the two different loads in two different chokes overlap each other and provide good pattern coverage from 25 to 43 yards. Also, these two loads use card and fiber instead of 1-piece plastic wads and are shot out of all brass hulls.
