Again chasing .38-55 load

[FromTheWoods]

We have moved, and my notes on the .38-55 have not surfaced. So, again I'll ask for your help.

The rifle is a '94 Winchester Takedown 7*** serial number, and wheeeee--a double-set trigger! I've checked Ken Water's loads. He lists an "Excellent load" to be 28 grains of RL-7 behind a 255 grain cast bullet at approximately 1600 fps. My bullets are from Montana Bullet Works 255 gr. RNFP and 250 gr. FN-BB--BHN15. Starline brass.

Other sources on the internet show RL-7 24 gr. = approx. 1400 fps, and 24-32 grains = 1400-1800 fps.

I was trying to work up a load for this rifle with Alliant 2400, but with the latest powder shortage, I don't have enough of it to do much shooting

1600 fps is faster than what folks recommend for shooting cast. I don't have a chronograph.
I would prefer accuracy over speed.

Any thoughts and cautions regarding this quest to find an accurate load would be welcomed.

I have a 336CB Marlin in 38-55 it likes 8.5gr of Green Dot with dacron filler behind a Houch NP 265 gr.

give GD a try if you have some.

An old 38-55 Winchester I had worked well with AA 2495 and the standard lyman 260 grain FN boolit. BvT

Use SR4759 or IMR4227.
If you want a heavier load IMR4198 should do.

38-55 barrel diameters and chamber sizes are all over the map. groove measurements can run from .375"-.383" and chambers are sometimes too small to allow proper sized bullets to fit. My 1894 has a .380" groove but i had the turn .001" off the outside of the brass case neck so i could chamber a .381" bullet.

What type of fps are you getting with this load?
