I don't have the book, but Hornady publish a reloading manual. I'll bet you can find what you are looking for there.

Our Moderator Brian Pfleuger said it very well here.

Brian Pfleuger said:OAL listed is completely and utterly irrelevent. If it fits and functions in your gun, go with it. OAL listings serve no purpose except to fit in your magazine and stay within SAAMI specifications.
Seat the bullet either so it fits in your magazine, or is a reasonable distance from the rifling to start. In all likelihood, you can't get near the rifling and still have it fit in your magazine.
I wish the books didn't even list OAL. It serves only to confuse the new guys. Nobody else pays any attention to it.
Longer OALs in rifle cartridges actually almost always INCREASE pressure, because the bullet getting closer to the rifling increases pressure more than the larger space for the powder to begin burning reduces it. It's a small difference until you get close to the rifling though.
JTxBrass, I loaded some A- Max 168 in my 308. Mostly shoot 168 SMK when I tried the A-Max knowing the distance to the ojive , the A- Max didn't chamber. I have very little free bore . Set to OAL 2.800 book specs, worked fine though seated deeper then my Sierra's I normally shoot . I did lower my charge by 1.0 grain , grouped just as tight as sierra. Using IMR 4064 41.5 gr. With sierra 40.5 with Hornady. Hope this helped.
The Hornady manual says they loaded it to 3.230" COL for their testing in .30-06. As the others have explained, you can put it where it best suits your gun, but the published number is a reasonable starting place.
Note that while one caliber into the case is a common starting point of reference, some bullets have bearing surfaces shorter than that, so you have to adapt to the situation.
