A Starting load with a 158 at 1487fps? Man that sounds kinda hot. I believe I'd double check that one. There is a lot of data out there that needs to be reduced by 10% and worked up to. This info is usually in the fine print. Underloaded cartridges are dangerous also so you have to be careful on both ends of the spectrum. It sounds like that data needs confirmation from another source. I sure would.
