Looking at setting up my .257 Bob for whitetail and antelope hunting. I don't want to set it up for any long range shots, just a med range of around 300-400 yds max. I'm shooting a Ruger No. 1 1-B (26" bbl) with a Vari-X II 3-9x40 AO. I am thinking about running some Hodgdon Hybrid 100V. So my question is, what bullet do you think would best suit my purpose? Looking for something that will penetrate well, being a fairly light caliber. I have looked at the NAB, Interbond, SST, and one of the Nosler Partitions, just can't decide.
