Such adjustments are trivial when the scope's adjustment dials have a MOA scale printed on them, and even figuring the right number of clicks is relatively easy on scopes that click in fractions of MOA. This makes zeroing and adjustments much easier: To adjust a 1 ⁄ 2 MOA scope 3 MOA down and 1.5 MOA right, the scope needs to be adjusted 3 × ...
20 mm / 50 m = 0.4 mrad, or 4 clicks with a 1 / 10 mrad adjustment scope. 50 mm / 1000 m = 0.05 mrad, or 1 click with a 0.05 mrad adjustment scope. In firearm optics, where 0.1 mrad per click is the most common mrad based adjustment value, another common rule of thumb is that an adjustment of 1 / 10 mrad changes ...
Granular material can range from very small colloidal particles, through clay, silt, sand, gravel, and cobbles, to boulders. Krumbein phi scale ... 0.50 < < 1.00 ...
A poorly-graded soil is a soil that does not have a good representation of all sizes of particles from the no. 4 to no. 200 sieve. A poorly-graded gravel is classified as GP, while a poorly-graded sand is classified as SP. Poorly-graded soils are more susceptible to soil liquefaction than well-graded soils. [1]

20 mm (0.79 in) crushed stone, used for construction aggregate and landscape applications. Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers.
The telescopic sight had a field of view of 8 degrees 20 minutes and featured a bullet drop compensation range drum on top of the sight graduated in 50 yards (45.7 m) increments from 0 to 1,000 yards (914 m). Side adjustments in 2 MOA increments were made by the drum mounted at the side of the sight. These rifles were designated as the No. 4 Mk.
River gravel is a name given to gravel composed of small pieces of rounded stone of various colors, usually no larger than a large coin. [1] It is named for the effect of many years of rounding of the edges of the stones due to a flow of water over it, as often takes place in a river . [ 2 ]
