Yep Bob; Starting new shooters on Quiet loads is probably the best gift you can give to the odds of them continuing on as a shooter. Of course adding ear protection always. In the Kinetic energy Equation, Velocity is squared and mass is simply multiplied. Fast or slow recoil matters to the shooter. I can certainly tell the difference. That is why heavy guns "soak" up recoil and light ones really "kick." It's the speed they hit you at. The load in the barrel was the same.
