Bob,
I have not not really worked up any good loads yet but what I shot are in the middle of the Marlin lever action load data from the Lyman Cast Bullet book.
At 25 yards it will put 2 rights and 2 lefts about 2" apart and only about a 1/2" different in elevation.
If my memory is correct, I ised IMR 4198 but I would have to check my load data book to be sure.
