The only reason to buy a Bob these days is sentimentality. They don't fit most actions well, and the .260 Rem is all over the .257 ballistically. Just compare your reloading guide for the Bob and .260. Ballistic coefficients are generally identical, powder charges the same at 35 - 40 gr, but the .260 is giving you an extra 100 to 150 fps. Now i am probably as big an advocate of the x57 cartridges as anyone here, but there is no way in the world i would go a Bob anymore - it just doesn't make sense. The .260 is also a cartridge of very high intrinsic accuracy and currently holds a bunch of trophies and records.
The .260 is as sexy as a fridge, but it is simply the better cartridge. It is truly one of the best cartridges of the last 50 years.
