.348 Winchester (using Hornady bullets)

Author: Brian Pearce / Wolfe Publishing Co.
Date: May 30 2013

The .348 Winchester was announced in 1936 in the new Winchester Model 71 lever-action rifle, a modernized version of the Model 1886. The case is based on the .50-110 Winchester, but is tapered, with a shoulder, and necked to accept .348-inch bullets. Early factory loads were advertised to push a 150-grain bullet to 2,920 fps, a 200 at 2,535 fps, and later, a 250 was offered at 2,350 fps, with all velocities being rather optimistic. For example in referencing vintage ammunition in a vintage rifle (with 24-inch barrel), actual velocities for each of the above were around 50 to 100 fps slower than claimed speeds. Regardless, it is a great cartridge for hunting big game in brush and timber.

Cases should be full-length sized, then checked for excessive length and trimmed as needed. Primers should be .003 to .005 inch below flush. The 200-grain Hornady FP bullet should be seated to an overall cartridge length of 2.785 inches, then crimped in place to prevent bullet movement when loaded in tubular magazines and subjected to recoil. Cases that are uniform in length will produce the most uniform crimp.

Several powders gave excellent accuracy, with notable results coming from Hodgdon H-4895, H-4831, W-760 and IMR-4350.
