Introduced in 1978, the 375 Winchester is close to being nothing more than a modern, high-pressure version of the, circa 1884, 38-55 WCF. It does have a few minor differences. Chiefly, besides having a much higher working pressure, it uses smaller (0.375-inch diameter bullets) compared to bullets closer to 0.378-inch in the 38-55. Case length is also slightly shorter. This was another of Winchester’s efforts toward modernizing Model 1894 chamberings, in an effort toward boosting waning sales. The attempt proved ineffective. Few folks were interested in a chambering that combined significantly greater recoil with more bullet drop. Despite a lack of commercial success, the 375 Winchester is a fine chambering for hunting species up to elk with shots inside about 150 yards. With the 375 Winchester, as with all cartridges used in guns with a tubular magazine, a properly applied crimp can smooth and ease chambering and a crimp is critical to lock the case mouth into the cannelure and thereby prevent recoil and chambering forces from driving the bullet into the case. In some instances, a roll crimp might be the best option but the Lee Factory Crimp Die usually does a better job and the crimp it applies will not damage a cast bullet as chamber pressure drives that from the case. Heritage of this case dates to 1879 with the introduction of the 38-50 Ballard case.
