I'm most likely younger than you having retired late last year but definitely not young. When I explained my rapid fire situation and posed a question a few years ago on this forum looking to reduce smoke I was mostly met with comments like "I could care less how much it smokes as long as the bore stays clean." I got a few really nasty responses for asking the question.
Dirty powder never bothered me. Loaded ammo that's sticky from lube and has to be cleaned before using it is a slight bother but cleans up pretty easily. I've rolled around in the floor working under my share of cars and been greasy up to my elbows so not afraid of "a little dirt." When I load cast boolits into ammo I have come to appreciate powder coated boolits because they keep me cleaner, the loading dies stay cleaner and the action of semi-autos stay cleaner through a match. Lube smoke isn't an issue if I'm shooting a single shot or repeaters slowly. Ammo that doesn't have to be cleaned after loading is pure luxury as is not having lead residue embedded in my fingers.
The flip side is, in a worst case scenario, shooting a match looking into the sun with the face of the targets in their own shadows and with little or no wind. When I've been practicing and shooting a lot I can shoot 4 to 6 rounds per second on closely spaced targets which are frequently in clusters of four. That's a lot of rounds (and smoke) in a very short time. When the sun backlights that smoke the targets are completely obscured. THAT is when smoke is troublesome. I have actually had to pause a string of fire so I could see the targets again. That costs places in a match.
Shooting powder coated boolits not only reduces the smoke to almost nothing but also keeps the gun clean enough through a two day, high round count match so I don't have to clean it in a hotel room. Using powder coated boolits with the same charge of the same powder shows that almost all of the fouling was from the lube.
Shooting cast through my Contender in .44 Mag the old 2400 leaves a lot of powder residue and it's certainly not from a lack of pressure. If it bothers me I can fire a round or two of .44 Special with the same boolit and lube but Winchester 231 and it's clean as a whistle; no need for further cleaning. No idea if the mag load smokes; always too busy recovering from the recoil of a 255 grain boolit at 1600 fps.
It's not about sensitivity for me; it's about better scores at matches.
