The Cartridge Families poster visually simplifies the vastness and complexities of hunting cartridges available in the US. The world’s vast array of cartridges can actually be broken down into basic family groupings. Each family group share the same parent case…although the parent case has probably been modified to achieve a new or different result. Cartridges within the family can easily be organized from least to greatest in caliber, velocity, power, and recoil. By knowing the parent case (size and features), it is simple to determine the overall power potential of a given cartridge in addition to where it lies when comparing it with cartridges of other parent cases.
This poster takes six of the most well-known and influential hunting cartridges displayed at 200% scale so its easy to identify the shared case. These 6 cartridges are the 223 Remington, 30-30 Win, 308 Win, 30-06 Springfield, 300 Winchester Magnum and the 378 Weatherby Magnum. We then picked four or five popular cartridges (at 100% scale) and arranged them from least potent to greatest within that cartridge family.
