Wondering why Hodgdon publishes StaBall 6.5 load data for .300WSM but no .300WM

[wombat13]

I load on a Dillon 550, so a rifle powder that meters like a ball powder is very interesting. I've seen Walkalong's results metering with his LNL and it looks good. Definitely would be nice not to hand trickle stick powder. They claim it is temp stable as well.

Anyway, the burn rate chart published at https://imrpowder.com/resources/data-sheets/ shows StaBall next to Hybrid 100V. StaBall is right in the middle of powders that are frequently used in .300WM and they publish data for .300WSM, so I wonder why not for .300WM (which I'm pretty sure outsells .300WSM by a considerable margin)?

They may have not tested it yet. With all the different calibers to test they have to pick the most popular to start out with. Give them a call they may have and not published it.

If I do call them, I'd ask the same about Superperformance. It is slower than IMR 4831 and H4831, but faster than RL22, IMR 7828, IMR 7977, H1000, Retumbo.

Superformance is in a "special class"... There are many applications for which it will work just fine, but Hodgdon won't publish loads. The reason is a contractual one with Hornady, for whom the powder was developed. That is to say that Hodgdon won't publish a load using Superformance unless it shows at least a 100-150 fps speed advantage over other listed powders in that application. But if you call them, they'll give you load data anyway, assuming they have tested it.

Just called, but they're closed on Friday. I'll give them a call next week.

I remember seeing data for 300wm using Superformance. It barely beat imr4831. It's no longer listed.
