Don't think so?....put down your pistol gripped rifle, and grab a straight gripped one in the same chambering, same weight category. You can feel the snappy torque reaction. You can SEE it taking place while spotting, if your shooter doesn't have a good solid hold, just watch the muzzle.

I can buy into home registry, based on that.
Your call.
