Two caliburs....10 slow, 10 timed, 10 fast..

Some of this may be tough. I have a 22LR 10 shot semi-auto (a real tack driver), 1911 45 acp 7+1 ( 4.25" barrel, semi-accurate), 357 7 shot 2" snubbie (not a target gun), 357 single action Blackhawk 6 shot (very accurate), .22 WMR 8 shot revolver (very accurate) and a .454 Casull 6 shot Ruger SuperRedHawk (a very accurate wristwrecker).

I'd go with the tack driver and the Blackhawk with .38 wadcutters.
