300 gr. bullet question

[furface]

Good Day
I have some .44 cal. 300 Gr. cast bullets I want to load for my Ruger Redhawk 5.5" and 7.5" Bbl. . I will be using 2400 powder. What I am finding is loads starting at 13.5 grs. to max of 20.0 grs, what i want is a load of around 1100/1150 fps. any help.

Do you own a chronograph?


Assuming this is a .44 magnum, somewhere around 18 grains of 2400 should reach 1100 fps. in a 7 1/2" barrel, but you need to work up from below. Without a chronograph, you'll only be guessing at the velocity.
