factory ammo velocity

every now and then i wonder to myself, how do factories produce ammo that produces velocities that are around or sometimes faster than book maximum for reloaders and know that it is going to be safe in everyone's rifles?

we are always told to approach maximum loads with caution, but factories can produce maximum velocities that are safe in any rifle?

do they have 'special' powders or something?

interesting to see if anyone can shed any light on this.

Re: factory ammo velocity
not being a chrony owner but having read a heap of stuff over the years and reloaded for 20 + my take on it is this
the velocity figures they "claim" are often as real as distance to target we do.........
the figures they reach are often from test barrels of much longer length than std sporter and if ave 30-50fps per inch it stands to reason their velocity will be higher
they are also using virgin brass so have wee tad of ......... room for extra pressure???? not quite worded right but its not been pre stressed so should be stronger?????
hornady superperformance and light magnum ARE using special powders and blends that have small window of great performance these arent available for reloaders to use
