- Is that in fact Eastwood black chrome?
- Could you (please) post a pic of the result ?

To be honest, the Lee Universal Flaring Die does it all -- all calibers.
Specific M-Dies are great, but get the Flaring die no matter what

What are you sizing it to after coating?

Has the OP looked at Alliant (BE-86/Sports Pistol) data?

"Hardcast" without an actual BHN# is absolutely meaningless.
(Caveat emptor comes to mind)

I powder coat most every thing now....
except bore riders.

Those I deliberately ALOX to great effect.

There are likely other testing options/suggestions...

With the (Lee) die super-clean, no issues w/ bare lead
(within reasonable 2-3 thou)

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.

(That said....)

Given that "burn rates" as usually listed in the various rainbow charts are only the start-point rates...
... and those rates change with...

See above belief that (true 90/5/5) Lyman #2 is not affected by quenching.
...and that I would re-check.

I recast both air cooled and fast-quench (direct from hot mold into ice water) RotoMetals...

Bottom Line:
No Problems

Binary Lead/Tin alloys aren't affected by either quenching or aging.
They are effectively what they are, near immediately, and stay that way.

Ditto actual Lyman#2 at 90/5/5 Lead/Tin/Antimony....

I see the (less-than-1/10th-of 1%) silicon to be residual from the gross ore smelting process.

Pure lead (RotoMetal) comes out at 4.5-4.6 BHN.
Reactor Grade lead just a decimal point lower

5.7 - 5.9 BHN (Rotometals * )
Not only the Lee tester/scanner reading the impression -- same readings over multiple samples, multiple years, three different testers. **
....but the Materials...

Forget the Scope (for now).
Just put it on your printer/scanner at 9600 px/in and reading the indent diameter becomes a no-brainer.

When you say "low," what is it apparently reading for the alloy(s?) you've tested with it ?

If (now) close to 60 years ago that Speer#5 would have been talking about IMR4831 -- as it existed then
