55 grain gmx and 9mm critical duty

[Morgoth]

Noticed on Doc's latest "Terminal Performance Spreadsheet" that the Hornady 9mm Critical Duty in standard pressure is now on the list,he also states the TAP 55 grain GMX is acceptable(I carry it in my AR15) on par with 62 grain TBBC,64 grain Nosler,and the 50 grain BH TSX,am curious what prompted him to include the 9mm? It's what I carry in my EDC/CCW XDM 4.5.Any thoughts on it vs the +p version? Any input is appreciated

Morgoth, could you provide a link to the referenced spreadsheet?

Thank you for that link. I see that others are catching up with the 62gr TBBC's level of barrier-blind performance. I have 40 rounds of 55gr 5.56 pressure Superformance GMX on the way. I'll see if I can can get some H2O shots into water jugs in the next few weeks.

You can find the TAP GMX for $22 a box, its able to be used in short barrels and gas systems, superformance is intended for rifle length setups

That was from his first test and the 9mm CD did NOT make it to the "list",however a more current "list" shows the standard pressure 135 gr 9mm CD listed with HST etc,I'd like to know what OIS/CIS propmted this change for my own interest.
