The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically the largest, with 39 inches clear for the aperture.The second largest refracting telescope in the world is the Yerkes Observatory 40 inch (102 cm) refractor, used for astronomical and scientific observation for over a century.
The Rhynland rood (Rijnlandse roede) was a standard Dutch measurement.It was changed in 1859 to the "Cape Foot" due to a drift in standards. 1 Rhynland foot (Rijnlandse voet) = 12 Rhynland inches (Rijnlandse duim) = 1.030 English feet.

For reference a 1 MOA circle at 100 yd (91 m) has a diameter of 1.047 in (2.7 cm), 3 in (7.6 cm) at 100 yd (91 m) equals 2.9 MOA, and 5 in (12.7 cm) at 100 yd (91 m) equals 4.8 MOA In summary the accuracy standards of the Gewehr 98 and most other service rifles used in World War I and later were similar.
An overview of 7mm caliber cartridges, their history, and uses in firearms.
The subsonic bullet also has a larger maximum diameter of 7.94 mm compared to all other 7.62×39 bullets that peak at 7.91 mm diameter; the larger diameter of the lead-core section was intended to provide a tighter fit to the barrel by better engaging the rifling grooves.
