Only 308 guns that I've spent a lot of time with was an M1A and a rebarelled M1 Garand. They both realy liked IMR 4895. On the other hand, most of the guys that still use the 30-cals for matches swear by Varget.
FWIW..... Nosler makes a dern-fine bullet but if your gun has a 1-10 twist, me thinks that you'll get better accuracy with their 165 version.
Hope this helps.
