I checked my notes for my 300 WSM. The load was actually 65.0 grains 4831sc with a 210 touching the lands. Norma brass, and a CCI 200 primer. Velocity averaged 2710.

This is the same velocity I was getting with a 230 Berger OTM loaded with 7828ssc in the same rifle.

Got the 215 Hybrid shooting from one of my WSM's 30.25" barrel and a Really hot load for winter time hunting.
3022fps

*gotta love RL17

I had a great load with r17 for my wsm. The accuracy wasn't as good as the h4350 but was still sub MOA. And the speeds we're great. But I noticed different speeds and different pressures depending on the outdoor temp. It just wasn't as stable as I would prefer. Im sure your aware of this but just be careful if your still shooting that load in the summer

300 WSM 210 VLD
H4350
Starting load 53.5gr @ 2450
Max 59.6 gr @ 2700

The max load could possibly be exceeded as no 2 rifle chambers are the same. I'm over listed max in my 300 RUM by a full 3 grains.

Keep us posted during load development.

Loaded my first round of 300 WSM shells a couple weeks ago. First time I've been able to get to the range was today.

I put a new Nightforce scope on so I zero'ed with factory ammo. Then I tried my loads. From what I read in many threads many were having consistency with H4350 so I thought I'd start there. I have a 1/10 rifling and wanted to shoot a heavier bullet so I thought I'd also start with the 210 Berger. Factory ammo shot MOA so after I was zero'ed, I went to my new hand loads.

Powder Ranges from 57.5 to 60 grams in .5 increments. Primer was WLRM in once fired brass - Federal and Winchester.

Best round for me was 59.5 with a 1/2" group at 100 yrds. Seems like something I can work with.

I don't have a chrono yet so I'll have to guess but comparison to Eastcoastshooter and Hodgdon charts (using closest weight bullet 208gr Amax) should put me in the 2700 fps range. I'm not going too long range with it yet but I think I can use that inside 300 yards for a hunting trip this weekend.

Cool looking round with the 210 Berger in that fat case!
