Last week I dusted off my Vanguard 308 and put the Barnes to work. I had some odd headstamp Winchester brass a guy at work gave me awhile back. I had some W748 left in a bottle and put it to use. One thing I can tell you Barnes load data is off , it list W748 49.4grs to 54.9grs with Win. brass. 54.9 would be running over the top. I started at 49.5 was at 3060fps went up a 1/2 a grain til I hit 3139fps at 52grs. At 52 I was up the neck a ways , I stopped there. Tried them on paper and I’m set on this.
