I prefer 2400 in all of my 44 magnum loads. I shoot 300gr Hornady XTP's mostly now. I tried some Nosler sporting handgun 300gr jhp's and had some issues getting the bullet to seat due to the case being too full at maximum or near maximum loads. The lead nose of the bullet would form to the seater and sometimes crush the edge of the jacket. I tried other powders with that bullet but accuracy wasnt there. I went back to the Hornadys and the bullet construction helped me compress the heavy powder charge without hurting the bullet. With 240gr bullets a charge of 21gr 2400 will do quite well and always yielded good groups from my redhawk if you should decide to go with a lighter bullet. I like the big ones better myself. I dont mind recoil, i guess thats why i shoot a S&W 500 so much.
