Here is the texture:

I've never used the prilled form.
Also, I don't see any mention of Magnesium.
What does the front of the package look like?

Here's the front.

I use Dynamite Select CRF which does contain Magnesium, FWIW.

Basically my question is - if magnesium is a non-issue, will this "work" for pH purposes, and at the "same" dose as typical 5-1-1? Or do I have to adjust it?

Should I crush the "prills"?

This is basic high quality agricultural lime that does not contain Mg. I would put the "prills" in a glass of water and make sure they break down. I assume the lime is just pelletized to make it easier to apply with a fertilizer spreader. They should break down when they get wet. You could crush them to make the lime spread more evenly but I think it would be a lot of work for little actual good. This should work fine in the mix, just will not add Mg like dolomite lime.
