I don't have a book with me but a good start would be to seat to the crimping ring and go from there. Often that's as good as anything,

Seat your bullet where it looks good to you, the cannalure is as good a guide as any. If it feeds from your magazine and chamers without jamming into the rifling (it will) that's all you need to start.

If you had some book OAL value it would only be what the book makers used to develop the listed charges in their rifle, not a law for everyone else. You would still have to start low and only muve up if you see no signs of overpressure anyway.
