I just ordered some myself. For the speed you get from their shells, coupled with low published pressures is a pretty good combo. Also, if the patented Gordon recoil reduction system reduces actual recoil by 10-15% as B and P claims.....well, I just think that is HUGE!! Holland and Holland recommends those shells in 12ga for use in their guns because of the low chamber pressures. So, they must be pretty good shells. I've shot a few of their shells and they seemed very good. I will know more when I get through a couple of cases.
