Hi all, can someone explain the range data on the disk and plate for me? The rifle is a M1896.
Thanks so much!

Disc information only valid at time measurements and observations were taken.
1. Torped (unmarked) = No difference between point of aim and point of impact when using m/41 bullet.
2. Bore measurement = 6.53mm
3. #1 marked bore condition (1,2,3) = "one or just a few dark areas in the corners between lands and grooves"

Also, refer to information on Dutchman's excellent web site ..
"The most common of the bore discs. The range of numbers from 6.46 to 6.59mm refers to the diameter of the bore. The increments are very nearly spaced .0004" apart, or 4 ten-thousandths of an inch.
This disc is marked at 6.52mm. The pie-shape with 1-2-3 refers to the amount of -rust- observed in the bore, though I've never seen -rust- in the bore of a Swedish Mauser. This disc is marked a #1, which is better than #2. The Swedes had certain standards for acceptable wear in their rifles, but it's almost unheard of to see a Swede barrel that's worn out.
The lower section is mostly unused. "Torped" refers to the boat-tail 139gr m/41 bullet. "Overslag" refers to over shooting, and the "str" is abbreviated for streck. There are 6300 streck in a circle. One streck equals .1m at 100 meters. This is really an indication of how high a bullet will strike the target in relation to point-of-aim."

Avstand means distance, the other thing is the adjustment for the rear sight. The sentence above means that it's the scale for point bullets (not sure if this is the right English term, means that it's no round headed bullet).
The original m/96 rifle used the m/94 156 grain round nosed bullet and the sights are calibrated for that bullet.
The Swedes changed to the m/41 139 grain spitzer bullet in 1941 as it gave better ballistics, so some compensation had to be made when using m/41 ammunition in the m/96 with the original sights.
The rectangular range plate gives this compensation. A Streck is a Swedish measurement of length, equal to about 3.6 inches. The left side (Arvistad) is the range to the target, and the right side gives the sight setting and compensation.
On this rifle, for example, from 100 to 250 meters, you would set the sights at 300 meters and aim 3 Strecks (about 10 inches) low to hit your target if you were using the m/41 Spitzer ammunition. If your target was between 350 and 400 meters, a sight setting of 300 would place the bullet on target.
