Does the Hy-tek coating effect BHN hardness

[GSP7]

Does the Hy Tek coating make a 12 bhn lead bullet act like a harder bhn rated bullet than uncoated

For example a .44cal 240 grain Kieth style SWC 12 bhn, would a coated (HY-Tek) bullet perform like a harder BHN, than same 12 bhn bullet uncoated?

NO. The coating has no bearing on the BHN.

never bought coated before so I dont know what its like...Thought it might be like hard plastic and effect mushrooming

A uniform coating must have some effect on the performance of the bullet.

What if you threw a peeled orange, versus an unpeeled orange against the wall? I would think if they hit at the same velocity, and mass, the peeled one would splatter more. Not the best analogy. I would think though that a uniform covering, particularly in its entirety, would affect bullet performance some way.

Without the same deformation, does it "act" harder?

I would think though that a uniform covering, particularly in its entirety, would affect bullet performance some way.

I would think the coating will effect mushrooming and expansion in some way also

IF you quench the boolit before coating and rely on the extra hardness quenching gives you then yes both HiTek and Powdercoating will affect the end hardness because baking the boolit to set the coating will take most of what you gained by quenching.

If you quench after the last coat, you can gain much of the extra hardness back.
