At the risk of opening a can of worms, the overall length isn't what you need to be concerned about, to a point. What is critical is the amount of bullet taking up case space. Too deeply and you can increase pressure dramatically. With a pointed bullet, I'd seat as far forward as I could and still keep one caliber in the case. Your limiting factor will be the ogive, not the tip of the bullet. The further out, the less pressure you'll get. Try about 0.003 short of the rifling. You can even seat to where it's just touching the rifling but be aware that if too far forward the bullet may "pull" if extracting an unfired round.
