Medium Bore (Proprietary & Wildcat) - Cartridge Poster


The Medium Bore - Proprietary & Wildcat poster displays cartridges from .333 to the .395 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. This poster is an excellent reference for any unique firearm project. The project could range from building an excellent long range or dangerous game rifle to modifying/improving an AR platform with a standard cartridge but increased caliber. Yet another could be maximizing a pistol cartridge fired from a Thompson Contender type platform. This poster helps guide the "What if" or "Could I make this" question/conversation for the gunsmith or the individual looking for a unique or an unanswered performance requirement.
