Put a new barrel on my 84M just for kicks. This means new load workups... I had good results with Leverevolution and the 210 Partition and wondered how it would do with a 200gn bullet. 51.5gn of LVR and a 200 Hot Cor resulted in a single 3-shot .58" group with a velocity of ~2700. Need to shoot it a few more times to see if that's consistent and refine the velocity. The 180 Accubond has been my nemesis. On a whim I grabbed a bottle of Benchmark to try. Turns out it likes it reasonably well. One group at .78" and 2773 is a good start.
