But they also rise dramatically if seated too far out. A safe load with the bullet not touching the lands may become unsafe if they are seated out far enough to contact the lands. The bullet with a running start before engraving the rifling causes less resistance than one seated out touching the lands already. Weatherby Magnums are noted for their long leads (bore with no rifing ahead of the throat). This leads to lower pressures much the same as loading a bullet farther out in the case. In effect it increses the size of the chamber.
