the montana gold used for the DT 9mm loading is a poor expander. very shallow cavity. barely increases diameter of bullet. if this is the standard design it may as well be a fmj in a 10mm.
when i get my G29 i will do some target shooting with it and my G20 with some DT 165gr. Gold Dots and DT 135gr. Noslers.

Facts are no match against enthusiasm and ignorance...
