There are many cartridges today that originated with the 30-06 case. It has a .473" casehead.
When you stand a 30-06 next to a 280, you'll notice they are the same case -with one necked down to 28cal. A 260, 243, 6br, or 22-250 are the same 30-06 case formed shorter and necked to cal.
Same .473 head shellholder for all
