The key concern That is still for me is how the primers effects may well fluctuate involving various cartridges, bullet weights, and powder masses. It's always been my impression that lower ES/SD correspond to optimized combustion; that is to state if the primer, cartridge quantity (force mobile), powder demand, were all optimized to give ideal combustion for any supplied bullet bodyweight. It is actually past issue that switching primers can generally improve (reduce) ES/SD using a provided load.

Working with CCIs are like poking marshmallows inside of a parking meter ... They're so difficult they flatten just before seating. Winchesters aren't far better but Remington or Federal tend to be more pliable and seat devoid of flattening.
