I decided to try and figure out a load for .308 win that my Savage 99 likes. Decided to go with the IMR 4166 powder. I bought into the advertising and hype. The reviews seem good. I read a good write up on Chuck Hawks on this series of powders. Has additives to reduce copper fouling and it is supposedly impervious to temperature changes. This will help when I work up a load and sight in during the summer then hunt during the fall. The grains are smaller then normal imr stick powders as well so should help with metering. Anyone got any experience with this enduron series? I will make another threw later on when I get to shooting it.
