Actually, I hand load .45ACP in 1,000 round batches. I do have a mouse gun, Kahr PM9, but don't shoot it enough to justify loading for it.
My point is slightly different:
"Performance" street cars are IMO silly because it is impossible to actually use their performance potential. (We all do silly things and buy silly things for fun, of course, so I am not criticizing buyers.) Most performance cars, and certainly the exotics, are really "ego cars." Again, if that floats your boat ...
From 10,000+ miles of wheel-to-wheel (SCCA) racing I can tell you that performance street cars are like kissing your sister. About all you can do is sneak in a few bursts of speed while running alone on a highway. Speed by yourself is boring; I looked forward to relaxing on straightaways when I wasn't in a drafting pack or in other traffic. At-the-limit cornering, even alone, is fun but on the street doing this is beyond silly, with curbs and other things to hit and with untrained drivers around.
"Track days" are not much better but that's really OT. OTOH, autocrossing can be a lot of fun even even driving a grocery-getter like my WRX. Big horsepower is not required.
