A gentleman in another thread asked about load data for the 470 Empire (tweeked my interest, so looked in that) and this got me thinking about my method of using Quickload for cartridges with no load data or no pressure data (such as Weatherby cartridges). Hartmut Broemel (the developer of QuickLoad) suggests modifying Ba and WF paraneters
to match a cartridge's published velocity and pressure data.
Since it is a wintery day here, thought I should look into how well the fit holds.
Using Hodgdon load data for the 30-06 with H4350 powder and max. charge, I matched the velocity and pressure by changing Ba and WF. It is a little back and forth, adjusting each one separately, etc. until a match. I do this a lot, so now it is quite easy to find the numbers.
These charts show the results of this computer exercise (we all know that barrels, throats, bore can impact real world results but hey, my computer is perfect
.
Have fun!
