Seems like Reloader 7 and 1680 were the powders I used when I loaded for one.
I had one of the distributor run Ruger 77mkII Ultralights, with the boat paddle stock.
Seems like I loaded the 125 grain Sierra for it too.
Good luck finding any Accurate 1680 or WC680. I think you would have a better chance of picking up Pixie Sticks with your buttcheeks.
I have some stashed but after I load 7.62x39 again the barrel will be dry. It is absotively the best I've used with 123-125 grain soft point Hornady bullets in my mini 30.
