When you say trust, I assume you mean for self and home defense. I trust just a few in that category:
Federal HST
Speer Gold Dot
Remington Golden Saber
Hornady XTP
Sig Sauer V-Crown
Underwood
Okay, so more than just a few.
I've been a Remington man for ever.
....I find properly stored ammunition from a reliable maker is amazingly reliable, apart from .22... some Remington 500 packs of .22 I bought a decade or so ago which have about a 5% failure rate...
Honestly, in over 50 years of shooting, I cannot recall a factory center fire cartridge not firing.I wouldn't need all 10 fingers to count the number of factory duds I've encountered in the last 50 years.
