I have used 8 grains of Unique and a cast 200 to 225 RNFP grain cast bullet in Winchester cases and a large Pistol primer. This load is listed as a moderate load in the various loading manuals and is considered safe in Winchester 1873 pattern smokeless powder vintage rifles.
I got this load from CF members here about 6 years ago, you can use the search function for the discussion. This load seems to be a sweet spot for fun shooting and after trying loads hotter and milder see no reason to change.

Hello Fotis, I shot 12 grs of AA#7 powder in my original '73 Winchester in 44-40, yes, .427" cast bullets are what I used too, sized down from 44 mag bullets at 240 grs and .430" Velocities were in the 1200 fps range in the rifle, shot through both shoulders of a doe so fast at 55 yards she didn't know what hit her, she stumbled then trotted 35 yards and crashed in the leaves.

Edit to add, loads were developed in new Starline cases, and WLR primers, also, the bullets were of the round nosed flat point variety.

Everything that I have read about the .44-40 indicates that the primer pocket was cut for large pistol primers. I believe that the LR primers are taller and could cause issues in a tube magazine.

I never had any trouble in my rifle 30, but good to know nonetheless.

Lil'gun is the last powder that I would use in that rifle/cartridge combination.
It proved inconsistent for me in the .22 Hornet Savage 23D.
