I went to the range yesterday to site in my new rifle. Wind was erratic and gusting at times. I worked up some loads for the 129 gr Hornady Interbond with H4350 (42.5 gr, 43.0 gr, and 43.5 gr) and for the 125 Nosler Partition. Overall length was 2.825" for all loads. It took 3 shots to get it on target to shoot for groups. I shot the Interbonds first, and they all shot just over an inch. For some reason, I just have a hard time getting Interbonds to shoot well. I noticed it shot better with more powder however. Then I shot the Partitions. I was not impressed with the first group at all with 43.0 grains of H4350. The group tightened up a little with 43.5 grains. The 44.0 grain load shot sub MOA with no pressure signs at all. I wish I would have loaded a 44.5 grain load to see what it would do. The 44.0 grain load is a keeper right now. I'm going to try to get to the range sometime this week to see what a hotter load will do.

I have no chrony speeds. I had 3 batteries and all of them were dead.
