What is the shelf life of .44 Magnum ammo?

Properly stored .44 Magnum ammo typically remains reliable for 10 to 20 years, though some sources suggest ideal storage can extend this further. Keep rounds in a cool, dry place away from moisture and temperature extremes. Consistent storage conditions matter more than bullet type.

What is the most accurate 44 Mag ammo?
