Hello, Im a new guy here but have been reloading for a while and need advice on casting for magnum velocities for a .300Win.Mag. Im having great results with my pistol and 30-30 boolits but not sure where to start with anything over 2500fps. If anyone can give advice, I would appreciate it. Im shooting a Remington 700BDL in .300Win.Mag. and have 99% lead, WW, and lino type lead to cast with. I am using a Lee production pot with a ladle and an older Lee bottom pour. Thanks in advance and if more info is needed, Please let me know.
PS- The mold im going to use is a Lee 90369 with GC.
