Being only for varmints 6x47, 6xc (something just shorter than 6creed and 243win), 6BR/BRA, 6ppc (you get the point) along with 22cals of similar cases.
knowing how far/max distance you'll be shooting this would help on caliber (and cartridge selections).
22cals that could give you the longest barrel life (if looking for that) wouldn't be a 22creed/220swift/22-250rem, but a move up in caliber would help.
i've used 5.56, 243win, many 26cals, 6.8spc and 22mags on varmints. each have their ups and downs.
