I've spent the last week or so developing a new load for my .260. I wanted to shoot the Berger 140 Hybrids. I've never had load development go more smoothly. I looked for pressure with some old brass and found the upper limit quickly. Then I used the OCW method to settle on a charge weight. That took just two quick trips to the range. Finally, I tested my final charge weight for seating depth. It all went exactly as planned with no confusing data to screw with my head. I took it out yesterday to measure actual drops at distance. We shot it at 500, 725, and 900 yards. I had my head up my ass at 500 and screwed that distance up, but laid down a 2" group at 725 and a 3" group at 900. The bullet is slow so it's going to get blown around a bit, but performance like that is hard to argue with.
The tape is on the group at 725. The 900 group is below left.
