History
Originated as wildcat around 1912 by A.O. Niedner and Charles Newton, necking .30-06 to .25. One of the oldest and most popular wildcats, widely used for 50+ years before commercialization. Remington finally standardized it in 1969 and it became immediately popular. Combines flat trajectory with mild recoil. Dominant western varmint and deer cartridge. One of the most successful wildcat-to-commercial conversions.
