Don doesn't miss much! 1oz reload in 12 ga. Remington greenie hull: 1.5 oz. Traditions brass snap cap (in which the piston fails to return after a few uses and has to be driven out and dressed to correct): 2.25 oz. Propelled by the steroid-boosted spring of a Southgate, they're moving fast enuf to make a dent in drywall. Activa homebrewed: no registered wgt. on either an oz. OR gram reading scale. No cost; no appreciable wgt.; less deformation of the pencil eraser than of the brass piston; no dessicant and no forcing cone tickler; and I don't use them anyway. Occasionally something which appears less complicated is less complicated.
