Home Forums Reloading Big Game Rifles Trying 130gr TSX in 300 RUM and need load data

I would like to use Retumbo, but it might be a little on the slow side. I also like IMR-7828 which is slightly faster, but I can't find any load data for these powders. Any suggestions? I am trying to avoid using my supply of 4350 since this case takes 90+grains in this caliber and I have a lot of H1000,Retumbo, and 7828.

.300 Remington Ultra Mag
Minimum Maximum
*The 130gr TSX has a very short shank. We recommend lightly crimping the case mouth with a
factory crimp-style die to increase neck tension.
*Powder charges of less than 100 percent density are recommended when loading 165-grain
Banded Spitzers, because of the length of the bullets.
