Need help finding load data for the new Hornady CX bullets.

[Sasquatch807]

I just got a box of 180 grain Hornady CX bullets to replace the GMX bullets I used to load my 300 RUM. I find myself unable to find any data for this new bullet. The Hornady website offers an App for this but I am not equipped for that and the new manual is out of stock. Does anyone know if I this new bullet uses the same data as the GMX it replaced?

I would expect it to be very similar to the GMX bullet it is replacing. It sounds like they've just changed the formula from gilding metal to copper?

But like any time you change components, start low and work it up. If there are any differences you'll figure that out during load development.

Yes! Thanks so much, I can confirm that the data is the same with the two powders I use.

Much obliged.
