C'mon guys what are we talking about here? Popgun loads. You can't put RD behind anything heavier than 1.125 oz. anyway. So one gun gives some long-necked type faceslap and a mouse under the eye and a guy with a bad shoulder needs a Reactor falsie to precent volume target loads making it act up and your 12 yr old thinks it sort of hurts the first time because she expects it will and maybe there's not enuf flab to soak it up. It takes approximately 160-200 of those Remington Goldies going 1330 to give even a little feller like me a nitro headache and my shoulder's hardly sore the next day. Have I ever had a "sticky" trigger and staggered forward from the line? You bet? So the neural system is making decisions to avoid an accumulation of minor traumas. Seems like some shooting Doc should have hooked himself and some buddies onto an EEG looking for evidence of varying neurological response to a given, calculated recoil force created by whatever propellant and payload might be revealing. A cf. of slow powders might be in order and maybe payloads 1.25oz or heavier so we're certain we're not just complaining about raising the gun to the shoulder a few hundred times and squinting into the sun.
