Use Lyman it should be fine. I use 24.3 for 60 grainers. Keep looking for pressure signs along the way.

I generally use the powder manufactures website for my loads...

But it’s wise to look at a few load manuals and see what is being recommended. I would also pay attention to what they use as their test weapons (barrel length, twist rate, primer, COAL, and case)

I use Sierra reloading manual..It's been good for me.
