I just started some development with the 195 in my 7PRC. In stock form, has a very reasonable FB. Promising first impressions. Next up will need to run ladders.
That reamer was created around the 215. Should be able to push 3k with N565 or H1000.
You CAN run 245’s, but with that FB in a 22” barrel…2900 is a tall order. You’ll still buck the wind, just not quite as flat of a trajectory.
I recently picked up two 8lb kegs of Retumbo for $349/ea @ LGS. 2 separate trips. Lowest I’ve seen it in a long time. But had also picked up some online before this find and paid $425 with shipping/hazmat. Mild offset I guess.
