Buffalo Bore's Heavy 38-55 Winchester ammunition brings serious stopping power to one of America's most respected classic cartridges. The 255-grain semi-jacketed flat point design delivers devastating terminal performance by combining controlled expansion with deep penetration through bone and dense tissue. This load generates approximately 30% more energy than standard factory 38-55 ammunition, transforming the cartridge into a formidable big-game round for hunters who demand reliable performance from their lever-action and single-shot rifles.
Unlike typical factory 38-55 loads that push lighter bullets at modest velocities, this ammunition launches the heavy 255-grain projectile to approximately 1950 fps with 2153 foot-pounds of muzzle energy. The semi-jacketed flat point design ensures the bullet maintains structural integrity while passing through heavy hide and bone, then expands reliably upon impact. Real-world field reports show sub-inch accuracy at 100 yards from lever-action rifles, with hunters reporting clean one-shot kills on whitetail, mule deer, and elk at hunting ranges.
This ammunition feeds smoothly through Winchester Model 1894 rifles, Marlin levergun platforms, and modern single-shot rifles chambered in 38-55. Buffalo Bore also confirms that this load works reliably in 375 Winchester rifles, giving owners of those harder-to-find calibers a legitimate source of high-performance ammunition. The modest recoil, compared to magnum loads, makes it comfortable to shoot all day at the range or during extended hunting expeditions without fatigue.
Each box contains 20 carefully manufactured rounds using premium brass cases that feed reliably and are reloadable for those who handload. The ammunition is loaded to Buffalo Bore's high standards with exacting quality control, delivering the consistency serious hunters expect.
Yes. Buffalo Bore specifically manufactures this load for use in both 38-55 and 375 Winchester rifles. The .377-inch bullet is designed to slug down to .375 caliber when fired without raising pressures. Buffalo Bore has sold hundreds of thousands of rounds with excellent results in 375 Winchester chambers. Always verify your specific rifle is in good working condition before firing any ammunition.
Field users report sub-inch groups at 100 yards from lever-action rifles, with many achieving 1-1.5 inch five-shot groups at 50 yards. The flat point design feeds smoothly through lever mechanisms while the heavy bullet weight provides excellent stability downrange. Accuracy will vary depending on your individual rifle, barrel condition, and shooting technique.
This heavy hunting load works well on deer, elk, and similar-sized game out to around 200 yards. The 255-grain bullet delivers deep penetration and reliable expansion for ethical kills. It's particularly effective in thick timber and brush where lever-action rifles shine. The controlled recoil makes follow-up shots manageable if needed.
Yes. These rounds use premium brass cases that are reloadable. The cases are manufactured to exacting standards and can be reloaded multiple times following proper reloading procedures and safe practices for the 38-55 Winchester cartridge.
