The 10 mm master list is missing the Underwood 150gn Lehigh Xtreme Hunter solid copper
also the 100gn solid copper
also the 115gn solid copper xtreme Pen
sierra jhp 135 with power pistol 8/19
and 180gn Bonded JHP w/longshot
all underwood

Yes there was a time when the old forum was running, and the data may not have been added by the person that was making the master list project.

I have assigned myself a task to migrate the master lists from Google Sheets where they are in the ownership of previous forum members to our planned WIKI:  wiki.10mm-auto.com.  I have already moved the pull-down master data sheet there and updated the links.

I will try to work on this over the weekend.
