Other than the lead free area's, I can see one other use that would be beneficial. I would think most everybody knows you can get by with less weight per caliber, due to nearly all mono's having near 100% weight retention. With that, for some shooters where typical lead core weights, might be a bit much in the recoil department for a given caliber. Going with the lighter copper bullets may help, say for instance a small framed lady or yongster. Where just for sake of discussion, one normally uses a 180-200 gr in a 30cal for elk. With the copper, a 150 gr. would perform almost the same. Cost for me really don't matter if it fills a need or has purpose. Beyond that it pretty much just a personal decission. Most would think I'm a bit off keel too, for using Nosler Partitions in most everything except for varmint/target guns. Are they necessary all the time? No.
But I have all the confidence in them, and I figure their extra cost is small for the reliability they provide. Hunting ain't always as cheap as hunting out the back door, so I don't worry about the bullet/ammunition cost, with all else considered.
