If published load data says that a particular charge will generate 2700 fps and you get 3000 fps, is that an indicator of excess pressure?
Sometimes,...sometimes not.
How would "you" know this?
Can't have excessive velocity without excessive pressure. Just the way it is.
That's not an absolute. Generally speaking, load manuals list loads at a given, industry standard pressure.
Power Pistol is only two positions below Unique on the powder burn rate chart. Yet Power Pistol gives quite a bit more velocity that can be achieved with Unique in many handgun chamberings despite the fact that they're very close in burn rate.
