winchesterpoor,
My first .264 was a Westerner, and after considerable experimentation I ended up using Ramshot Magnum with 140's at around 3225 fps and very good accuracy.
My present .264 has a 24" barrel with a 1-8 twist, and I've experimented with it even more. Magnum is most accurate with 125-130-grain bullets at around 3250-3300, but Reloder 25 is most accurate with 140's at 3100-3150. Retumbo also shows promise, but I haven't had the chance to experiment with it as much as I'd like.
