I understand the 38/44s were designed for heavier loads than the 38 special. Some of the guns apparently have been modified to take 357. Has anyone worked up modern equivalent of the old 38/44 loads? None of my manual show it. I now load both 38 and 357 and wonder if the 38/44 load was somewhat comparable to the current 38+P. Thanks for any info.
The old Lyman #43 manual showed .38 Special loads "For heavy frame guns" that ran in the 25,000 PSI range.
.38-44 IS .38 Special, just loaded to higher pressure. Current +P limit is 20,000 PSI, .38-44 loads were significantly above this limit and even higher than the pressure level indicated by the old Lyman book.
The best bullets to use to replicate the .38-44 loads are Lyman 358156GC, 357446, or RCBS .38-158 SWCGC. Load them as follows:
6.5 gr. Unique w/standard primer
11.0 gr. 2400 w/Fed 200
Note; Alliant specifies a Magnum primer with 2400!
7.1 gr. 4756 w/standard primer
Any of the above will get you in the 1150 FPS range with a 6 1/2" barrel and 1115+/- with a 5". If you have a chronograph, and you are just spitting in the wind if you do not, start with these loads and adjust as needed to get to ca. 1115 FPS with a 5" barrel and you will be very close to what was once published for .38-44 factory ammunition.
The .38-44 was never loaded with jacketed bullets by the factories. There was a metal-capped bullet. If you try loading jacketed bullets you need to settle for about 100-150 FPS less that with cast to stay in the appropriate pressure range.
If you are not already aware, velocities can vary drastically from one gun to another. A good example is 11.8/2400.158 SWCGC. I have chronographed this and had velocity range from 1086 in one 5" revolver to 1236 in another 6", far greater than the usually referenced 25 FPS per unch of barrel. It is also common for factory ammunition to chronograph significantly slower than published velocities, often by as much as 150-200 FPS!
