The biggest "quirk" with the 257 Roberts is when folks want to use it in a short action and find that longer bullets cannot be seated out. Many don't seem to find this to be a problem at all. I just had mine made up on a 700 long action was was easy able to make 3" OAL ammo with room to spare. Both the 25/06 and 257Roberts are very good cartridges overshadowed now by the CMs and PRSs.The .25-06 has all the good attributes of the .257 Roberts without the quirks of short throat/long magazine found in some rifles.
