Mark Dobrenski has used the 63 Sierra on a bunch of big game from the .22-250, including a big black bear he killed with what Elmer Keith used to call a "raking shot." The bullet basically went corner to corner on the bear.
Damn good to hear MD, no wonder that old Man is shooting through those deer and pigs, he has two cool old Browning's in 22-250, a Safari grade and BAR, when I found out he had a BAR I told him to buy a couple extra bags of brass ; ]
