Funny, I was just comparing the external ballistics of the 195 Hybrid at 2850fps from a 7RM or WSM (QL says I can get there without too much trouble) to a 300gr MK from a .338LM fired at 2800fps, out to 1 mile. The 7RM drifts less in the wind at 1760, and arrives with more velocity. The energy figures, while purely academic, are 730 ft-lbs with the 195, and 930 with the 300gr MK bullet. Not a huge difference between the two, despite the .338LM starting out with a lot more grunt at both ends of the rifle.
I would honestly grab something like a Krieger, Rock, Smith, or Gaillard in 7WSM or 7RM in 8 or 8.5" twist, throated for the 180gr Hybrid or 190gr Matrix VLD (the closest things we have to the 195 right now), and rock on in preparation for the new 195. The 0.794 G1 or 0.406 G7 BC of that 195gr 7mm Hybrid is tough to trump, even by a .300RUM pushing the 230gr Berger Hybrid at 3100fps, or the .338LM pushing a 300gr MK or Lapua Scenar bullet at 2800-2850fps...
