Personally? No. I would rather have a properly Jacketed bullet than a plated bullet, without a true Jacket I'd be concerned about less than ideal penetration on the larger animals. Probably a good coyote round, but that would be my limit I think. Also, those are limited to 1700 fps ... without checking my books, that seems a little slow to me for what I would want in a hunting load.
Never tried them ... no experience with them ... just my thoughts bassed on the info provided in the link.
