This 6-lug bolt would also then allow the owner to select something even harder hitting, say 9.3mm x 62, or very flat-shooting, like the .25-06. The bolts for mini length cartridges (like .223) uses three lugs, while most short action cartridges (i.e. .308) uses six lug bolts. The four main types of bolts and some of their factory calibers are:

;Magnum calibers, using a 6 lug bolt:
