Chaz, you will love 6.5 Creedmoor. I'm not sure that you'll stick with VvN15 though. I'm just working up some loads using IMR4350 and will put results up shortly. Everybody in't US raves about H4350 but it is unicorn droppings here. IMR is made by the same Australian mill and is supposed to be identical, but there is no end of boring debat in the forums on this.
Good luck--enjoy!
