RL 26 is not recommended for the .308, but RL 15 will do what you want. What bullet weight are you loading for?Anyone have load data for reloader 26 in 308 Winchester ? I'm not getting the velocity I want with varget, case is stuffed full, still no pressure signs and not as fast as I want. I have a big jug of rl 26 and it has done amazing things in other calibers including 6.5cm so I'm thinking it should work for 308.
The problem the OP had was the Hammers PDR groove profile. They don't build pressure like a normal bullet. One has to "hotrod" as viewed from traditional bullets. He should have used IMR 3031, to AA2520 types.No matter which flavor of the month cartridge people buy, they always want to hotrod it to get more. LOL
