.33 Winchester

Author: Brian Pearce
Date: Apr 16 2020

The .33 WCF was first offered around 1902 in the Winchester Model 1886 lever-action rifle and was soon chambered in the Winchester Model 1885 single shot and Marlin Model 1895 (original) rifle. The cartridge was based on the .45-70 Government case necked down to accept .338-inch bullets. Cases can either be formed from .45-70 brass or purchased from Bertram.

Both the Hornady 200-grain FP and 200-grain FTX bullets provided good accuracy when tested. Hodgdon H-4198 produced the tightest groups; however H-4895 was similarly accurate but propelled bullets over 2,300 fps for the highest velocity.

Other than when used in a single-shot rifle, spitzer profiled bullets intended for .338 Winchester Magnum and similar bolt-action cartridges should not be used in rifles with tubular magazines. The exception to this rule is the Hornady 200-grain FTX with its rubber “spitzer” tip that was designed specifically for lever-action rifles.

A heavy roll crimp is suggested.
