I shoot a 264 and echo the comments on wasting meat. Need something to hold together better until you get 250-300 yards down range and they slow down some.
Yep; good buddy of mine ran 'em through... er... INTO... a medium sized hog in Texas from his 6.5-284 (so slower than the WM) and got no exit; core separated.
Of course we know that from inspection of a dead hog that dropped DRT, so they're not ALL bad...
