I have used my .308 win on a couple interior bears growing up in a small interior town. As a teen I didn't know that 180 core lots weren't good bear medicine so I just made due. Now I can load 200 grain woodleighs to 2550 fps out of my 20" barrel .308 win and have to imagine that is better than the green/yellow box stuff I used on grizzlies in my teens. wink
