I signed up for a black bear hunt over bait this Sept. Thought I'd take my old Guide Gun. I've got some reloads (300 gr. Hornady hp, 48 gr Re 7) that I hunt deer with. Would these be ok for bear at 50 or so yards? That is about all the recoil I want. I have a box of Speer 400 gr flat nose i can load up if I need to. I need opinions on what a good 400 gr load to use. I have Varget, Re7, Imr 3031, Inr 4198 powders that I can use. Thank you.
