This new powder from Vihat, 565, is suppose to be exclusively for 338 Lupua Loads. I have loaded a few 265 grain rounds with 80 grains of powder but was hoping that someone had some much more detailed info on this powder, such as max charges for 250, 265, 300. I downloaded and printed out the Vihat's reloading specs, but was hoping someone had some first hand experience with this new powder and what they think about the powder and best combination.
