As everyone has stated the nosler is a heck of a elk round but price can be a factor(35-40 bucks a box).I have had good luck with a cheaper brand,one you don't here much of in the elk hunting comunity.I shoot PMC 180 gr SP out of my 300 win mag,almost 3000 fps and plenty of knock down for elk.I have never had seperation of jacket and lead core and comlete pass through.I pay 14.95/box for PMC's,I do use noslers also in my other guns but these are handloaded custom rounds.
Try the PMC's I find them far better than Remington Core-loks.
