Anybody with a Hornady manual want to chime in with a recommended OAL for the 115gr XTP, and I imagine they have data for titegroup as well? He may not be that far off. If the OAL is decent he could still work up to 4.7gr and not have to pull 150 bullets that may very well be just fine.
Or do we just want to make sure the lesson sinks in?
The lesson being; don't load 150 rounds of a certain load until you are done
asking questions about that load!
