Drew,
If the pressures are not increasing what do you think is causing the increase in perceived recoil? (I'm assuming that you have not measured actual recoil?) Is it just that the AA loads have a higher velocity / load weight than the 2.5" shells that you are using? Or do you think that there is something "funny" going on that causes recoil, but not pressure, to increase significantly?
