Loaded gallons of that also, in 223 with 55 to 77 gr bullets. I still have two 8 lb'ers left.After posting, to late in the day to change. I meant WC846.
I bought a jug from a gun show reloading dealer for $80 about 12 years ago. I planned to load 223 with 75 gr bullets. He said to use BLC data at 10% less to start a ladder.
OK, those were used after metal and then white jugs. Have fun.The 842 and 846 are in black plastic jugs. Look like oil or antifreeze gallon jugs.
