I would go with a 225 gr. for elk or moose. A 250 gr. for brown bear. Barnes TSX, Nosler Partition or E Tip, Swift A-Frame, Woodleigh Weldcore SP, or 230 gr. Norma Oryx PP.
I would use the same bullets for elk and moose as I would for brown bear just 225 gr. The 230 gr. Norma Qryx PP would be a good choice for both.
Good luck.
