The even numbers (4, 6, 8, etc.) on the left branch of the leaf, indicate 400, 600, 800, etc, yards.
The odd numbered hundreds of yards (300, 500, 700, etc.) are on the right branch of the leaf.
The numbers rest on top of the lines to which they refer.
So, if you want to fire at a target 800 yards away, set the rear sight at 8; 1,000 yards, at 10; 1,200 yards, at 12, etc.
With the fly leaf up, ranges from 100 to 2350 yards can be obtained through the peep hole, K; from 100 to 2450 through the lower peep notch, J; and from 1400 to 2750 yards through the upper peep notch, G.
There is a horizontal line on the drift slide, across the peep hole, K. If the peep hole sight is used the sight is set by this horizontal line, which is set opposite the proper graduation (line across branch of leaf).
If the peep notch, J, is used, the sight is set by the short horizontal line—that is, on a line with the top of the notch.
If the peep notch, G, is used, the sight is set by the top of the slide, C, which is set on the proper graduation.
Care must be taken not to use one of the peep notches when the sight has been set for the peep hole, or not to do the reverse, without first changing the sight.
The sighting notch, A, used when the range is 2850 yards, is hardly ever used, because the rifle is very, very seldom, if ever, fired at that range.
