Well I found a partial can of 10 year old 4064 in the back of my cabinet. Worked up to 43.5 grains behind a 168gr matchking seated to magazine length and wouldn't you know it 10 shots went into 7/10ths of an inch. Anybody ever seen a 308 that didn't like varget? I had burned a 1/2 pound of the precious stuff in the last week tried every combination with it possible and 1.25" groups was the best it would do.
Well, at least you know now what powder to buy.
