Rifle Scopes : Is there a recticle for 204Ruger?

I have a Zeiss Conquest 6.5-20x50 w/ Varmint Z reticle on my .204 and love it.  Reticle is perfect thickness for varmints, and the holdovers marks match the ballistics of the .204 almost perfectly out to 600 yds IF the magnification range on your scope is set to 20x.  (The .204 is a little flatter/faster than the reticle is laid out for, so the bullet and holdover marks start to diverge around 600 yds, or sooner if you have the scope set to a lower magnification.)  The link below is for the Zeiss ballistic calculator -- play around with it a bit and see what you think.  The varmint Z reticle is offered in the Conquest 6.5-20x50, as well as the new Conquest 5-25x50.   (It's hard to tell from the Zeiss website, but you don't want the Rapid Z 600 or 800 for varmints, as those reticles are too thick -- they are sized more for big game and low light.)
