I would certainly think the 300 gr. XTP would work well - I have used the 250 grain and 300 Shockwaves on elk with good results the past couple of years; and have been lead to believe by several on this board that the Shockwave/SST bullet is nothing more than a Hornady XTP with a plastic tip.

Best proven-from-personal-experience bullet of all, from a terminal performance standpoint, is still the 250 gr. Barnes Expander MZ. I have used charges from 70 grains of loose all the way to three 50 grain Pyrodex pellets - all with good accuracy. Only thing about these pricey little bullets is that you may have to get some aftermarket sabots if they go downyour barrel too firmly. I have used the regular Harvester 50/45 with good results in my T/C guns. Others have reported easier seating with some of the MMP sabots. Good luck. Hope they let you hunt during the September rut like they do here.
