Ok! I've managed to confuse myself. What is the proper Brinell hardness when loading with black powder...thanks!

Sounds like you need more help than just bullet hardness:

With the sort of reloading you apparently aim to do, you probably mean to ask about Brinell softness. Most 'soggy' alloys will work fine, and anything that approaches hard is likely to cause trouble.
Just experiment with various alloys of tin/lead and leave harder ones, or treated ones out of the recipe. What John Boy pointed you to will help. 
Bullet fit is probably going to be more of the solution than anything.

Not going to cast bullets at this time, I'm going to buy them. 
most sellers show the softness/hardness of their bullets by Brinell number not by lead to tin ration, dont want to buy too hard or too soft just looking for some kind of guide line to go by.

Depends a lot on your bullet.

For Creedmoor type bullets with bore-riding noses, something between 4 and 8 does well for me.  For the less-well-supported noses, like Money bullets and paper patch bullets, 8 to 11 or so is optimum.

Some people do fine with any hardness (Lino-WW or any range scrap) with the bore riders; others complain of leading.

I tried water-quenched range scrap for paper patch bullets once (BHN 14 or so).  The results on the target were dismal.

On the contrary, 
I have had good results from midrange to long range BPTR
with my alloy of 9 parts WW plus 1 part Lino. 
Both with GG and Paper Patch bullets.
Just need to have the correct dimentions for Freebore/Leade/
barrel fit.

to add " for whatever the "H" the Brinell hardness may measure.

20:1 is 10BHN 
This is a good place to start. 

You'll have to try other ratios to see what your gun likes if the 20:1 doesn't give you the accuracy your looking for.

The Money bullets generally need 16:1 or harder to avoid nose slump.

Tell us which bullet type your shooting and we can do a better job of confusing you all of our free advice.  Cheesy

Actually I'm thinking about these.

Looks like they are casting with Lyman #2 equivalent for BH 15. Of the 2 you listed I would go with the Saeco which might be a better bullet at BH 10 (1 to 20). Since you would save about $50 per 100 by doing them yourself, a couple of hundred bullets would pay for a mould Smiley
