I would be very leery of the 1-1/16 ounce high pheasant loads. They are faster than they state and the pressure is substantial. No reason they should make a 2.5" shell that hot.

The 1 ounce version is fantastic and at reasonable pressures. The test data I saw indicated they are 500-1000 psi hotter than published on many of their loads. This info was discussed on the shotgunworld forum.
