Obsolete is: no one really chambers this cartridge anymore because something else has come along that is easier to deal with and performs just as well if-not-better. Kinda like the 7x57 Mauser or 7mm STW or 300 H&H.
Dan,
Ruger is still chambering the .257 Roberts, 6.5x55, 7x57, and .300 H&H.
Savage is also still Chambering the .250 Savage and the .300 Savage.
CZ 500 in the 6.5x55 and 9.3x62 can also be bought here in the US.
