Good Morning!

The number of variables found with standard reloading can be several while wildcats often increase that number. However, here is a thread from a few years ago which will lead you to a proper choice for your cartridge:

And in addition, here is an article about 7mm cartridges with a focus on the 7mm/300 WSM which is near the bottom of the article:

Enjoy the process!

H4350's pretty fast. H4831, H1000, Retumbo are probably more suitable. Otherwise just use 7mm WSM starting loads for your wildcat.

I use H4831SC with 180s. It gave lower velocity spreads than H1000 in mine using 210M primers.

Which Berger 180, what OAL are you going to load to, and which brass are you using? If you're set on H4350, I can work backwards from my load in QuickLoad.

Berger 180 hybrids Norma brass still working on OAL I did try some at 58.0 gr. H4350 no pressure signs and shot very well. I am also using CCI BR-2 LRP ( not mag ) 3 shot group cutting each other.
