You won't beat factory velocities by any significant amount, but you could better the accuracy. That's the advantage to reloading. You won't save any money either, in fact you'll probably end up spending more, but you'll also shoot more. I think if you're wanting to improve on ballistics, you ought to consider using a different bullet, one with a higher ballistic coefficient. Why is it you don't like the plastic tips? The 160 grain Accubond would do slightly better at 400 and 500 yards than the bullet you're shooting.
