Shot some targets today in Indiana - temp was about 30 degrees. Shooting reloads with 1 oz of shot in my Beretta 391. The loads are designed to be light ( I hate recoil ) but the shells didn't have much ejection " umph !" Is there a minimum shell pressure I should be striving for to get reliable shell ejection ? If so, I can recheck my reloading data. If not, I'll keep shooting the "light" loads.
