Never hunted Elk, but have hunted Red Stag in Argentina and quite a bit of African plains game over the course of ten safaris. The Red Stag went down quickly after being shot by a .300 Win Mag loaded with a 200 grain Swift A Frame, as have many species of African PG. Last year, hunted PG successfully with a .30/06 and factory loaded Barnes 168 grain TTSX.
Am also partial to the Woodleigh Weldcore, a bonded bullet that worked well on African PG. My 7x57 shoots their 160 grain pp quite well.
