Does anyone have any experience with the 370 Sako Mag, also called the 9.3x66mm? I've seen some Sako ad's listing that caliber, but haven't heard or seen much else. I contacted Sako about it, and they told me that it was developed for the Nordic countries to use on the big bears and elk (moose). They said it was basically a 9.3x62mm lengthened to as long that would fit in a standard '06 type action. They even sent me the case and chamber dimension diagrams to compare with the 9.3x62mm . Sure enough everything is the same, just 4mm longer to the shoulder. They also said something about it having a slightly higher operating pressure than the 9.3x62mm, about like that of a 308 or typical belted magnum. They also said that this and through the use of newer triple based high energy powders, they can get close to 375 H&H performance out of it. Of course by doing the same with the 375, they could increase it as well. Does anyone have any experience with this cartridge? How does it perform? I like the idea of 5 of those in a standard action.
