Much to my surprise, I found out that neither my Lyman or C-H funnels work with 300 WSM cases. The bottom of the funnel contacts the shoulder well before the constriction seals at the case mouth. I made a paper funnel for now, but what off-the-shelf funnels work with this case?
I trimmed the bottom of an old funnel to make it work.
Unscrew the plastic tip on a RCBS powder dispenser, hold on top of case. A normal funnel will fit over it and drop powder in the case. Thats what I did when I had a WSM.
RCBS makes a 22-50cal funnel.That one will work for you.
I had the same problem with my old RCBS universal funnel when I first started loading 270 WSM. I purchased the Frankford Arsenal set that has different removable inserts sized for each specific bullet diameter and it works great. This tool is one of those things that once you use you kick yourself for not getting one sooner. I think it cost 12 or 15$ which I thought was a bit pricey for a plastic funnel set but after using it I found it to be money well spent.
That's what I bought when I started reloading last year. It fits my 7 SAUM cases very well.

Same one I use. My old RCBS sits unused except when I'm loading pistol cases.
I like the short mags, I have a 270 WSM and a 270 Weatherby. The WSM doesn't give up much. I wonder if anyone has built a 270 Nosler?
The Satern 30 cal funnel works great for charging 300 WSM cases:
