Yeah from what I can figure Varget is AR 2208 as they have the same charge weights for the same velocity. charge weight in grams and grains as well as muzzle velocity in meters and feet per second. They shot well and i did kill deer with the berger bullets using this load. I have loaded for three different 7mm Mags, one liked H-1000, one likes IMR-4350, and one isn't too picky IMR-4831 to VV-165 using an assortment of Nosler bullets. Elkhunter111, I did see the "Extreme" logo on my bottle of Varget that shows both the sun & a snowflake indicating better-than-average temperature sensitivity. Most powders go the other way though, heat brings ugly pressure. ) I did not start with it as there is no Barnes data for Retumbo in anything other than 140gr, but RL-22 and IMR 4831 are listed as top powders in every weight from 140-175gr. I think your right on concentrating around H1000/RL25/Retumbo. (I use Retumbo in my. In some like the 7mm Rem Mag, there is little better at producing velocity for pressure than Retumbo anyway, so why would you muck around with temperature variance issues when you don't have to. RL17 proved to shoot a full 200 fps faster in this cartridge than either Hodgdon powder used. The temperature of the ammunition can be a big variable. IMR Enduron 8133 is the slowest burn rate in the Enduron family. Retumbo was good but got as good as 1000, RL-25 was awesome, but at the load he was shooting had temp sensitivity issues, going from mild to wild with a 20 degree shift up. Nothing yet but this is the load that will go to Southern B.
