The most accurate bullet that I ever tried in my Whelen was the 280 gr. Swift A-Frame with IMR4064. Don't recall the charge (it was a long time ago). They would go into little clover leaf clusters between .5"- .75" all day long. The drawback? They were ferociously expensive, hard to find around here and kicked the snot out of me. Thus, they never went hunting. I have no doubt that they would be deadly medicine for elk, moose or most anything else anywhere in the world.
My rifle, by the way, is a Browning A-Bolt, 22" RKS stainless tube with a 1/21 to 1/12 gain twist.
