I had an Idaho bear hunt booked for myself and my son for the first week of June of this year. The Kung flu has postponed it till 2021.
I had intended and still intend to use my Ruger SBH .44 with factory Federal Fusion 240s. I have been greatly impressed with the Fusions. A bear and then a deer taken with them last fall ranks as probably the two most impressive .44 Mag revolver bullet performances I have instigated.
If not my new favorite bullet(Fusions), I would use a perennial favorite of mine, the 250 Nosler Partition. Expansion and penetration makes blood trails and quick kills.
I will also STRONGLY recommend a fiber optic front sight on a hunting revolver. The green HiViz on my .44 has been a gamechanger for me. I can't imagine anything without glass working better on a bear at dawn or dusk, or in the rain for that matter.
