I would not want to approach one of those downed and have them charge ..they can literally shish kabob you.

I have killed dozens of animals with the old corelok. Reason I bought them was they were cheap and I was poor. My biggest complaint is they are rarely accurate. And if you measure thier dimensions or wieght them, you will find out why compared to a gameking. I know we will have a bunch of people getting on here talking about how accurate they are. But from my experience, its rare. I hope the ultras are better.

I agree with bigcountry, I have killed several things with the core locks... ALOT. But they never seem to be real accurate on paper out of my .270.

Inaccurate I don't know about the last batch of factory ammo I tried out was pretty darn accurate in my book. BC your kidding about Sierras on big game right? I am just trying to find out if these Ultras perform well on big game and if anyone has accuracy issues..

Ive never had accuracy problems out of the regular corelokts or the ultras out of my 270, I like the 130 federal sierras to on deer.

On deer, I think gamekings are a great balance of accuracy and terminal performance. I have great luck with em. Would I ever use em on moose or elk? No way. Partitions or my new favorite the Barnes TSX is used. The accuracy of Coreloks will work. I can regularly get 2 to 3" groups at 100 yards out of any of my rifles with factory coreloks. Like I said I used em for 15 years. But I never did care about getting one hole groups until 8 or so year ago. Now, 2" groups is a disappointment. I am not knocking the new ultras. I have yet to form a opinion on em yet.
