Here is a link to some data developed by Lapua:

9.3x66 Sako Data

I've always been interested in this cartridge and recently acquired a 9.3x62, with the intent of punching it out the x66. (I even ordered a x66 reamer, head-space gauges, and picked up dies.) However, after some additional research, I have decided against this planned conversion, at least for the time being. It just doesn't warrant the added head-aches.

I'm becoming more tolerant of intolerant people.
