As an example, I will point out, the 6mm PPC (still, one of Today's, "best" Bench rest Target, Cal's) with it's, 30 degree shoulder and .285 neck length to support a .243 dia. bullet. Any deviation "very far" from, the ONE Caliber, neck length "rule" gets, boycotted, with some like, the 7mm WSM,.. more than, other's. The longer Neck allows, a slightly "torched throat" barrel to be, set back/ re-chambered for, a bit more bbl. "Life", as the bullet can be set, further "out" and still be held securely in the Neck.
