John:

I don't want to hijack this thread, but this question is related. Just about everything I read says that the .280 is downloaded, or at least has a lower SAAMI-spec PSI limit, than the AI. I've also read that if the .280 is loaded to the same pressure limit as the AI, i.e., 65k, that there really isn't very much gained by going the AI route. So here's my question: You have a nice target-velocity schedule, based on bullet weight, for the 7x57 since that data has historically been all over the board. Do you have something similar for the .280? In other words, how much velocity should one expect by loading the .280 to the same AI pressure level?

I don't know if what I'm asking makes any sense, but there it is.

Thanks
