JLS,
Are you set on using a Barnes bullet? I ask because of all of the things I have read on the internet about them not expanding well at low velocities. I don't mean to start anything by saying that, as I really have no dog in that fight, but if you don't already have them on hand you might at least consider using a conventional bullet that is designed to work at a lower velocity, as the Hodgdon link explains. Also, I'm not aware of what manuals you have on hand, but if you want more powder options than H4895, and a velocity lower than the 2,900 you mentioned being listed in your sources, my Speer #13 manual has start loads for 14 different powders that range from just above 2,500 to just below 2,800, when using their 130gr. bullets. If you let me know what other powders you might be interested in, I'll look them up, and if they're listed I'll PM you the data. I realize it can be dangerous to mix data between different bullet types, but it would at least give you something to compare to the data that you currently have.
