COL listed in books is irrelevant for rifle rounds. Some books don't even list it and I wish none of them did.
The cannelure is irrelevant.
Load the round so it fits and functions in your gun, start at starting loads and work up.
The length of the case doesn't effect pressure you're seating the bullet the same. The space under it in the case is the same.
