Okay, so I'm pretty new to reloading (and to the forum) so this might be kind of a noob question, but I noticed something pretty weird the other day at the range. I normally reload with lapua brass and am getting velocities right around 2750. I wanted to load some more but all the lapua brass was already loaded, so I figured I'd just load up some Hornady brass I had lying around from when I had shot some of their factory match stuff. Went to the range and the velocities were consistently a full 350 FPS slower. I couldn't believe it. Everything was done the exact same: fire formed, neck sized, same charge, bullet etc. So my questions is if this is normal and why this would happen? I mean I know that different brass can get different velocities with the same charges, but 350 FPS seems like a lot... And I feel like jacking up the charge in the Hornady brass to get the same velocities as the Lapua would be sketchy as all hell.
