Waters

This cartridge was developed by the well known gun writer and ballistics expert Ken Waters. This is the result of his attempt to develop a flat trajectory cartridge for use in lever action carbines.

In 1983 U.S. Repeating Arms Company decided to chamber their Model 94 lever action rifle for this cartridge while the Federal Cartridge Company worked out the final version of the cartridge that became the commercial 7-30 Waters. Thompson/Center also chambered their Contender for the 7-30 Waters. It has become more popular as a handgun cartridge than as a rifle cartridge and is satisfactory for hunting deer and black bear at short to medium ranges.

The SAAMI Maximum Average Pressure for the 7-30 Waters is 40,000 C.U.P.
