For deer and blackbear? 140gr at 26 Nosler velocities is more than enough, and will shoot flatter, and will have less recoil than the 28 Nosler. While not ideal, A 26 Nosler will work just fine for elk, too.

How likely is that elk hunt? Personally, I wouldn’t step up to the recoil of a 28 Nosler just for a speculative elk hunt. Especially if the alternative is a 26 Nosler.
