Can't tell whether you mean "1 to 10 milliohms" or "0.1 milliohm", but I would think that even 10 milliohms is below the resolving power of even a very good hand-held meter, like my Fluke, and if measurable, differences of that magnitude could as well be due to dirt or oxidation on the conducting surface of either the meter probe or the contact point as to actual differences in R across the fuse.
Yet, I hate to admit it, but I've heard a difference between one fuse and another, once. In that case, the expensive fuse was not as "good" as the hardware store sample. Four other well credentialed audiophiles heard exactly what I heard that particular day and time.

Hi Lew
What I am saying is less than ".1" of a miliohm or 1^-4
You are correct , a standard VOM would never capture this and the source impedance of a transformer high tension winding might be 2-5 ohms in a typical amp
It's been a while but the impedance of the power delivery transformer and wiring back to your house from the pole is probably 1 ohm!
I do hear differences in cables- I attribute it to impedance interactions over frequency- that's my story

And I do use "audiophile" fuses, albeit not the glamorous ones (Acme silver cryo in Acme silvered fuseholders), when feasible and despite my own skepticism. Some things are cheap enough to accept on faith only.
