The only hunting failure I recall was Dad's Vanguard failing to fire.
Light primer strikes, on a full elk. He never got a bang.
The gunsmith said it was insufficient firing pin length. The pin looked ground off.
He bought it new, never touched it. Used it for 4-5 years, always factory ammo.
He discarded the empties, so may have missed a blown primer.(unlikely)
On a previous various hunt he had one misfire, a light strike. He pitched the round and killed a couple animals. It worked fine at home checking zero.
