Looking for 300 wsm case length after trim. and maximum overall cartridge length of the 300 wsm. Thanks

COL 2.860"
Case max 2.100" so trim to 2.090".

I'm out in leftfield here.

Do companies like Sierra, Speer, and Hornady have 300 WSM loads in their current manuals? I spoke to Sierra a year or so ago and they didn't have anything at that time. I think 300 WSM brass was not available maybe.

What's the latest? Do they have loads worked up, and if so do they have loads for bullets weighing less than 150 gr.?

One of these days I'd like to get my reloaders out of storage and work some loads up for deer and varmits.
