I've finally gone over to the dark side(grin) and have my first Nightforce on the way. I have a 300 WM it will go on for now. After doing some searching in the archives, I've found some very helpful information on the R2 but still have a few questions. It was designed for a BC of .495-.535 and MV of 3340-3420. Is anyone using the R2 on a 300WM and have a load and bullet that works well with the R2? Thanks Cowman
