Currently using 180gr in my .300WM. Caught two of them under offside hide of a moose at a little over 200 yds. Haven't weighed them to confirm retained weight, but text book mushroom. Easily punched through small blacktail ribs, just behind the shoulder at about 60 yds. Pencil in, 50 cent size hole out.

I had hoped to use them on an Afognak Island elk this past fall, but alas, no elk were harmed in the making of my "camping" trip! smirk
