Re: Berger 300 winmag 215/230 Target load data
Here is what I received from Berger:
The following tables should have the info you need:
One comment though, these tables were developed with a SAAMI COAL (3.340). With your extended throat, you may find that your pressures will be somewhat lower.

Load data was generated using QuickLOAD with a 26 inch barrel and a COAL (cartridge overall length) of 3.340 inches. Your COAL and velocity could be a little different.
AS WITH ALL RELOADING, APPROACH THE MAXIMUM LOADS WITH CAUTION, AS ALL RIFLES AND RELOADING TECHNIQUES WILL BE DIFFERENT. IF YOU CHANGE ANY OF YOUR COMPONETS: THIS INCLUDES DIFFERENT POWDER LOT NUMBERS; YOU MUST REFIGURE YOUR LOADS BY STARTING WITH THE MINIMUM LOAD.
Hope this helps, if you have more questions, feel free to fire away.
