Welcome to the forum.

The answer is no because it varies with every bullet maker. In general, manuals from a bullet maker will mention the COL's (OAL, COAL) they use with their bullets. Hornady, for example, gives a different one for each of their bullet designs in a given cartridge. But you need their manual to have it at your fingertips.

The major bullet makers all have 800 numbers. You can call them and ask what they recommend for a particular bullet? For a bullet that fits many chamberings, they may give a seating depth. You convert that to COL for your cartridge by:

COL= case length + bullet length - recommending seating depth
