      Great, looks good. Sometimes a little boost on speed will stabilize the boolit, especially the lighter weight one like this. We have found that the 115 JHP 9mm will tighten up around 1200 fps. Have to experiment keeping things in a safe range of course looking for sudden pressure changes or other signs you have gone too far. With lead pills you have to be especially careful particularly the swaged HBWC. If you run them too fast, can blow skirts off and get some pressure spikes. I have seen them come off and get stuck in forcing cones. Hard cast and good lubed boolits can be run pretty fast with relative safety and good results.
      Glad my suggestion had positive results for you. Keep shooting those groups and out um all in the center. A good shooter told me the key to being a good marksman is putting them all in the center. LOL
