100% reliable in a G35 (with weapon light), G22, and G27 so far. Accurate too.
Seems as good as the fodder in the pretty Tactical boxes.
Glad I bought 1000 rounds of it.

Nobody has piped in on this; so, I will throw in a few cents:
I called Federal and spoke with a technical person about the white box HST ammunition when I found some and wondered what it was.

According to the Federal tech, it is overruns of ammunition loaded for ICE. He stated that ICE required tighter tolerances on velocity variance than Federal's regular HST round. The other difference is the regular brass case vs. nickel plated.

Bottom line, per Federal: HST for ICE, tighter velocity specs, and brass, non-nickel cases. For all practical purposes, it is the HST round in non-nickel cases.
