Which of the following bullets would be your top choice(s) for black bear hunting in Maine this fall. I will be using a .45 caliber Ruger Bisley, and most likely buying my loads from either Buffalo Bore, Conley Precision Cartridge or Grizzly Cartridge (depending on the bullet I choose). Here are the bullets I am contemplating (in no particular order):

335 Grain Cast WLN
300 Grain Nosler Partition
300 Grain Hawk Flat Point (.035 Jacket)
300 Grain Hawk Hollow Point (.025 Jacket)
300 Grain Speer Plated Soft Point
300 Grain Hornady XTP-Mag
300 Grain Hornady XTP

Any help greatly appreciated, especially from those with experience with any of these bullets on game or in penetration tests, etc. Thanks a lot.
