Actually some are some aren't,
my 5 tins of .25's, 1-JSB & 2-AA are identical but 2-JSB's are a different batch & slightly different inside the skirt, all equally as accurate.
I'm sure I've seen a competition online where they ran, shot & ran again a bit like summer biathlon although that's on roller blades/grass skis.
HFT against the clock would be interesting & more realistic, because out hunting you have to shoot targets as & when you see them, you usually don't have time to relax & slow your breathing/heart beat.
