Buddy got a Performance Center 460 for Christmas and since I am his reloader I started trying to pull data together. Seems folks here like the standard magnum powders like H110 and AA9; seems the 250-275 grain bullets are the preferred; and I take it that the 460 uses rifle primers? None of my older reloading manuals has 460 included so I would appreciate any tips and tricks. How do you crimp? Roll, taper or do you get the Factory crimp die; let me know what's needed with the monster's recoil. Thanks in advance.
