Re-loading data for .300 WM

[Gert Odendaal]

Members any re-loading data for the .300WM. SONCHEM 365, ELD-X 178gn bullet, OAL 87mm , I commenced with 63gn S365 at 2430f/s that is not fast enough and was used to blow out new NORMA brass....
Are there any members that reload the same components for the .300WM that will share data with me please?

My only experience with Somchem was with the S385.

Is Somchem avalaible again ? I heard the factory burnt several times but how it is now ?

I'm not familiar with Somchem powders, so the following is just what I could find in a few minutes of searching:

Peregrine bullets provides a burn rate chart that includes them here.
At first glance, it looks like your powder might be a bit too quick burning for 178/180 grain bullets in the 300 Win Mag.
For example:
Hodgdon lists three loads on their data website for H1000 behind 180 grain bullets.
CEB Maximus, Nosler E-Tip, and Speer MT-SP
All three are ~2800 to ~3000 fps
H1000 is significantly slower than Somchem 365, and it isn't the slowest powder you could use in the win mag.

There are many other variables to consider, but powder selection would be where I would start.

SONCHEM IS up and running again..Unfortunately their price on the different propellants sky rocketed , in some cases it is more expensive than the imported propellants , many hunters moved away from SONCHEM propellants.
