found the standard 1680 info to work perfectly. The old Winchester 680 data can be used too. If I remember correctly I drop one grain from the Win 680 data.
1680 is a strange powder. In my 44 Auto Mag and 45 Win Mag Grizzly in a normal load with 296 or other than with 1680 when I fire a round the brass comes out red hot. With 1680 the brass is cool to the touch. Not sure why but it never fails to be cool.
