The Micro & Small Bore (Proprietary & Wildcat) poster displays cartridges from .085 to the .257 caliber. The cartridges are arranged from relative smallest cartridge type and case capacity to largest. Standard cartridges are placed intermittently to provide good reference to size, case dimension, shoulder height, and angle as well as neck length and over all case dimensions.
Cartridges range from Tini Mites, Fleas, and Squirrels (22 Long Rifle, 22 Mag, 25 Auto, etc.) up to the full length belted magnums (Weatherby, Remington, Winchester and H&H magnums) and non belted magnums such as Lazzeroni.
