I had no idea about this new round until this thread was started. I was thinking strongly about the 6.5 PRC so this one also interests me. When I had my 264 WM I ran it at the same speeds as the 6.5 Weatherby PRM 3000-3100 with 140's and 3200 fps with the 130 gr class of bullets.

Even if it isn't the most popular round Weatherby has a good track record of supporting their rounds. It will be interesting to see how it fares compared to the 6.5 PRC since they have essentially the same performance.
