Lehigh bullets in 10mm, STOCK III and STEEL models

[1911maker]

I could not find any good reloading data for the 140GR Lehigh bullets. 

The STOCK III poly barrel is returning consistently higher verbosity then the 0.25 inch shorter STEEL barrel.  I "assume" this is the polly rifling, but like input if any one knows more.

 

Powders tried so far:

Blue Dot

AA #9

BE-86

AA #7

Lehigh 140 and AA#7, 10.3 gr  1154 FT/sec

  This is faster with less powder then the Lehigh data lists.  I suspect the Lehight data has a miss print and am reluctant to go to the listed max.

 

Does any one have any other Lehigh bullet data?
