Yes you are right, I just didn’t make myself clear about the 7x57. I have a 30-06, a 8x57 and a 303( a couple actually) and they all do what they were designed for.Well, exactly.
Although I'd say the 8x57J (1888) started it all (rimless case) as it preceded the 7x57 (1892). Many magazine gun writers say the 7x57 because the US Army examined it after our encounter with the 7x57 during the Spanish-American War in 1898. That, of course led to the USA's .30-03 cartridge (soon followed by the .30-06 of course).
