I have a gen2 700 5R, and I got one pretty dialed. 46.8gr of 2000MR, bullet seated at 2.208 ogive, Lapua brass, and Federal 210M primer. I had tried seating them longer originally, but pulling them back tightened up the groups quite a bit, as well as the GM primers from CCI BR2's. I haven't tried them with Varget yet, but I really like the extra speed from the 2000MR. This load gets me a little over 2650fps, on a magnetospeed. On my first test loads with the powder, I ran them over 2700fps, but the accuracy wasn't there. The 185 Juggs are winners, though. I may sell off my 175 SMKs and stick to the Jugg.
