Remington .300 Ultra Mag

[TAM]

Here is an email I got from Walt at Berger regarding load data for the Berger 190's and 210's

 

Good luck!

 

Hi Tim,

Load data was generated using Quick Load a 26 inch barrel a COAL (cartridge over all length) of 3.600 inches and 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 COMPONENTS; THIS INCLUDES DIFFERENT POWDER LOT NUMBERS; YOU MUST REFIGURE YOUR LOADS BY STARTING WITH THE MINIMUM LOAD.

 

If we can be of any additional help feel free to contact us.

 

Thanks for your interest and have a great day.
