i guess i'm coming in this late i see alot of cartridges that are comon in the various list.My opinion of obsolete is have to either make your ammo or specail order an example the 401 winchester self loader you have to order or make you don't go to a gun shop and buy ammo for.A 30-30 you can go into any gunshop or walmart and buy.I have some obsolete plus some harder to acquire but not obsolete 22 hi power can buy but not obsolete 250-3000 " " 303 savage i'd call obsolete as well as 32,35,and 401 wsl but 151wsl is still availabe.Ihunt with a 308 norma mag but can still buy so i don't believe it qualifies
