Waaaaay too (unnecessarily :p)hard.
Go with 0.380"/30-1 (BHN 5.8) and obturate early just as the article indicates.

Unless you're grossly resizing (like 458 --> 452) I've never found lube req'd.

One of the reasons Lead/Tin alloys give good expansion is that that they are soft -- even at high (and expensive) tin ratios.
When actually measured/tested for hardness, 30-1 is ~BHN 5.8, and 20-1...

"Hardcast" without an actual BHN# is absolutely meaningless.

Just make sure to regularly clean out the cylinders after a lot of 38 brass -- prevent
carbon buildup at the mouth of the shorter case leading to 357 chambering problems.
