You got that right. I'll tell you one thing, those "cantankerous curmudgeons" might not be wasting as much ammo as you, but they sure as hell are putting each one in the black.
I would certainly hope so...
I'm guilty of both "styles" of shooting.
Sometimes I shoot slow, 100yd targets with the AR, or one of the other rifles.
Other times, I shoot the handguns, usually deliberate fire, about a shot every second or so...
I seldom do a magazine dump, as I can't hit very consistently that way. If I do that, it is to see how "controllable" my handgun would be if I felt the need to respond to a threat that way.
I would like to think that I would respond to a threat with deliberate, aimed fire, but, not having been in that scenario, I can't say I would, for sure.
