Understanding Shell Compatibility
Mini Shells (1.75″)
Mini shells are popular among Mossberg 590s users. These small rounds have less recoil and let you carry more shells. They’re good for situations where you need to move around easily and shoot quickly.
Good things about mini shells:
- You can fit more shells in the gun
- Less kick when you shoot, so it’s easier to aim again quickly
- Easy to carry and store, great for emergency bags or keeping in a car
- Not as loud, which can be good for hunting or home defense
Not-so-good things about mini shells:
- Might not feed into the gun smoothly without special parts
- Don’t shoot as far or hit as hard as regular shells
- Harder to find in stores compared to regular shells
- Might not stop threats as well in some defense situations
Mini shells are good for home defense in small spaces, teaching new shooters, and some types of hunting like small animals or pest control. They’re also great for people who find regular shells too hard to handle.
Standard Loads (2.75″ and 3″)
The Mossberg 590s is mainly made for regular 2.75″ and 3″ shotgun shells. These shells are versatile and can be used for hunting or home defense. They’re the most common type of shotgun ammunition and work very well in the 590s.
Good things about standard loads:
- Lots of different types available, like birdshot, buckshot, and slugs
- Work reliably in the 590s, feeding and ejecting smoothly
- Shoot farther and hit harder than mini shells, good for various hunting and tactical uses
- Work with most aftermarket parts without needing special adapters
Not-so-good things about standard loads:
- More kick when you shoot, especially with 3″ magnum loads
- You can’t fit as many in the gun compared to mini shells
- Make the loaded gun longer and heavier than when using mini shells
Standard loads in the Mossberg 590s show off what the gun can really do. They spread shot well and transfer energy effectively at typical shooting distances. The 590s handles these shells easily, cycling and ejecting them reliably even in tough conditions. For most people, standard loads will be the best choice because they’re versatile and work well in many shooting situations.
