[Bruceanderson93]

Hello I am new to reloading and have bought some 200gr hornady ELDX bullets. I am wanting to use rutumbo and can't seam to find any load data on the two together. Just wondering if anyone has anything on them

What cal are you loading for ?? Obvious a .308 diam cause that's all the ELDX comes in with a 200 grn pill. Need cal to get any other info for you.

93, per Hodgdon's data site starting 73gr and max 78gr for 200gr bullet in 300WM. Start low, work up. Good luck.

I feel like an idiot but I'm not sure what this is saying. The combo together won't work?

There is a lot to what you are asking about.

The book data is on Hodgdon's web site is for Nosler AB and Partition. A significantly different shaped bullet.

What is your COAL?

This will help the most in getting things right.

Apparently I need an update for my QL as I don't have ELD-X

I think you will find that Retumbo may be too slow a powder to get decent velocity with.
H1000 is the slowest that I can think of that would be good, 7828, Rl22,25, & 26 would be better.
