In my opinion there's no such thing as a least diverse cartridge, if you are a handloader and especially if in addition you are a bullet caster too. Cartridge diversity is a state of mind of a shooter. Armed with an open mind and willingness to think outside the box, any cartridge can be pretty diverse.
.38-55? One of the most renowned target cartridges of a bygone era, and loaded with a heavy cast bullet a wonderful deer load today for all but the long range deer sniper crowd. .22High Power? Better bullet selection today than when it was in its heyday- if you know how to find them.
