So when I look at data saying a max of 45 gr under a 150gr bullet I'm going to ask questions. That's a lot less. (Yes I get that the smaller bore means less bullet to push on)

I also know that with the brass I'm using 48gr is a slightly compressed load let alone 49 or even the 51gr I gave seen suggested of AR2208/Varget in a 308win family case.
So as everyone else has said, look at multiple sources for your reloading data and until you have an understanding of the pressure effects of a longer bearing surface or a thicker copper jacket or solid copper bullet work with data that tells you exactly what bullet they used and use the same bullet.

Greetings Z,
Rather envious of your .358 Win. My son had one which we loaded for using AR2206. I think this sits just a little slower than BM8208 based on test firings I did recently. He got a couple of packets of cartridges from Belmont for a start. These were loaded in unfired 7.62 cases that had been reformed and loaded with the Hornady 200 grain spire point that chronographed about 2,350 fps from the 24 inch barrel. Slow but effective. I also reformed R-P .308 cases. Since I have cases, dies and loaded ammunition I keep my eyes open for a .358W but no luck yet.
Regards Grandpamac.
