Quick load help

[Klem]

And how do you think they go about measuring, a compressed load if this is correct Kmon ?I think there using low case fill weights esp. where there is a partition or a e tip involved to cover their hind end from liability.

Scrape,

Who is 'they' in your comment: Nosler, or QL?

If you are referring to QL, it lists the 'Propellant Solid Density' for 8208 as 1.620g/cm[SUP]3[/SUP]. They've either got this from the manufacturer or gone about pouring powder into volumetric beakers themselves.
QL lists the rear of Barnes' 100TTSX bullets as 6.1mm small taper (base), 6.71mm large taper, and 2.54mm as length of taper (between the two). Boat-tail angle is 6.8degrees. With this info and powder density the program calculates the volume displaced for the OAL you enter. You can vary this default data if you want to do your own measuring.
