Would you figure something like a Nosler Partition in the 260 for elk, big bodied deer?
You would definitely want a premium bullet like the Nosler, since the .260 would be bare minimum for elk, I would think. There are a lot of good premium bullets nowadays. Some don't like the Nosler because sometimes the front end breaks off at the partition, leaving less mass to penetrate. I've heard the Barnes x-bullet doesn't have that problem because it is solid copper, and Swift premiums also have a good reputation for holding together. I'm not an expert on the subject.
