I've only used the 338-06 on deer and black bear. Don't think either new the difference between the 200 gr. Speer or 210 gr. Nosler Partition. If I was to go for elk or moose the price of the bullet would be a major concern. Lately I've been loading 210 gr. Partitions because the price was right at SPS. Just don't tell the bear that the bullet was a second.
