1st What is the viper bolt face dia and action length?
2nd What is the pythons bolt face dia and action length?
For bullet selection you cant beat the 30 cal selection, in a close second is the 7mm.
A few companies come to mind, Berger, Lost River, and Cautirico (sp?) that make fine custom bullets for the 7mm.
What case to use, well that depends on the action size and bolt face. I would consider using the Ultra series 30 cals or 7mm ultra, next on the list would be 7mm STW, 7/300 wby, or the short ultra/wsm series calibers.
Course barrel length will play an important roll in extended trajectories and seeing the benifits of such a long barrels.
My personal favorite is the 300 Tomahawk, I'm sure you've read the posts on it and seen its capabilities. I have built one and am still in the testing stages.
I also am fond of the 7mm STW as I have two and they are excellent rifles with custom bullets and handloads.
I also like the NXS for that matter any of the nightforce scopes.
My two cents. [img]images/icons/smile.gif[/img]
