Loads for .44/40:

(Note: These are near maximum loads, you should use 10% less to start.)

(See note on Powders below or read all about various Powders.)

Bullet sizes vary from .426″ for jacketed to .427″ for some lead in diameter. (Note .44 special uses bullets from .429″ to .423″)

Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up. However, this is a big case and with light loads of low density powder, case position is important. Suggest tilting gun to sky before each shot with very light loads. Stuck bullet reported with minimum load (May 2010)

These loads are for MODERN guns. Make sure your gun can handle it. Powder Mfgs. Velocities in a test barrel differ from a 4 4/5″ revolver by about 175 fps and from 7 1/2″ by 50 fps.

Discussion: The .44-40 Winchester, also the .44 Winchester, and the .44 WCF (Winchester Center Fire) was introduced in 1873 by Winchester. It was the first centerfire metallic cartridge offered by Winchester, and was the standard chambering for the new Winchester Model 1873 rifle. This is a bottle neck cartridge with the base of the case being .471″ in diameter and the neck is .443 in diameter and uses a .427″ bullet. The case is nearly the same length at the .45 Colt. The rim of the case head is nearly the same. You can hardly tell the difference holding in your hand, save for the mouth opening and slight taper. I have picked up several 44-40 cases thinking I was picking my .45 colt cases. The mouth of the 44-40 will fit inside the .45 colt, but it will not go past the bottle neck expansion of the case. For reloading, the case shell holder are the same.

This is a very old cartridge. It’s been around over 140 years. Do not use any of this data with gun designed for black powder loads. It’s best to use new brass so as not to get the old balloon head type used years ago. Some old cartridges also used corrosive primers.
