I was watching a vid on internal ballistics and they made an excellent point: velocity isn't free.
When you start to see similar MV to book loads, regardless of your powder charge, you need to stop b/c that's at max pressure. Pressure relates directly to MV (well, area under the curve but for a single powder, Press/MV)
Hmm... that could be why Hornady doesn't list data for it. Anyway, I can set up the labradar and take data.
