I screwed up

Thanks Bob, for the info.

I am attempting to wrap my head around the diameter of the poppet stem/head material, and how it effects the flow and performance etc.
It appears that very small differences, does make a marked improvement on the ballistic/efficiency end, what a learning curve.

A 1/8" = .125" diameter stem,
3 mm = .118" diameter stem (79 OEM),
3/32" = .0938" diameter stem,
 
with differences of .007", and .012" and .031", between them.

I will know from shooting tests, (pending), as I plan on testing each diameter stem, spec'd to the 79 stems/head etc,
using the same spec's I have now, with 3000 psi/1320 set point on reg, with both brass and Delron heads, for information gained on my end.

The results I have right now are,
with a standard OEM valve/poppet = 800 fps/14.3 gr  pellet, 3000 psi/1320 set point
and with a 1/8" stem/Delron poppet/valve = 830 fps, 3000 psi/1320 set point.

Waiting on more material/parts, for updating these above results.

Tia,
Don
