There's sometimes no simple answer for why a pet cartridge is not more popular with more shooters.
The 6mm Remington has better ballistics than the .243Win. but back when the 6mmRem was introduced, the rifles had the 1:12 twist and only shot the lighter bullets. Winchester introduced the almost identical caliber - .243Win. - (but with slightly less case capacity) but they rifled their guns with a 1:9.5 or something close to that so it could shoot the 90 and 100 grain bullets & advertised it for deer, antelope and varmints too 'cause it was capable of shooting as small as 55 -60 grain bullets. By the time Remington offered 1:9.5 twisters, the race was already won by Winchester.
With the .257 Rob'ts, the field is crowded with really great calibers like the .25-06 Rem., .25 WSSM, .257 Weatherby Magnum and the old originater of the higher velocity .25 caliber rounds, the .250-3000 Savage.
