I have hunted Black Bear before with my 300 Win Mag shooting 220gr R.N. bullets at 2700 FPS and got it cleared thru Serria because they were Serria bullets. You know what Serria said "The round nose bullet will not mushroom and will go streight thru the Bear at those FPS. Nothing about it comeing apart. So I used them. I was thinking maybe the Hornady 250gr R.N. bullet would do the same. Will find out
soon I hope.
