How many factory rifles currently chamber the 260 Rem?
Slightly more than in .257 Bob.
There is nothing inherently wrong with the .257 cal, it is just that it is very clear there are much better bullet options available in 6.5mm. There are probably some very good custom makers for .257, and at that point the Bob might start to be competitive. It is also interesting to not that the 6.5x57 is very popular in Europe - same case but using the better 6.5mm bullets. It is probably the most sensible option, but i'm not aware of it having ever caught on in the US.
