Thread: Old Data and Load Variations. Traps for New Handloaders

Greetings,
The .264 Win Mag was ahead of its time in 1959 but hampered by the projectiles and powders available at the time. IMR4350 was the slowest cannister powder available with only milsurp powders that were slower but not consistent from lot to lot. This, together with overtight barrels and long bearing surface projectiles made the .264 cranky to load and only 3 years later came the 7mm Rem Mag. Today things are different and I think the .264 was even chambered by Remington recently. Better projectiles and powders have changed everything.
