Magtech 55gr Range Ammo FAQs

What twist rate works best with this ammo?

Magtech 55 grain FMJ ammo works well with a 1:9 or faster twist rate. Specifically, most factory AR-15 barrels ship with a twist rate suited to this bullet weight. Slower twists like 1:14 may not stabilize this bullet properly. Therefore, check your barrel’s twist rate before choosing this load.

Is this ammo safe to fire in a 5.56 chambered AR-15?

Yes, Magtech 55 grain FMJ ammo is loaded to 5.56x45mm NATO specifications and is safe in any properly headspaced 5.56 chamber. Additionally, it also safely cycles through .223 Wylde chambers. However, shooters should avoid firing 5.56 ammo in a rifle marked .223 Remington only. Always verify your barrel markings first.

Does this Magtech 55gr range ammo use reloadable brass?

Magtech 55 grain FMJ ammo uses boxer-primed brass cases that are fully reloadable. As a result, handloaders can recover and reuse spent cases after firing. In addition, the non-corrosive priming keeps case necks and primer pockets in good condition. This makes it a solid choice for budget-conscious reloaders. For a bulk case format instead, see our Aguila 55 Grain Battle Pack load.

What velocity does this ammo produce?

Magtech 55 grain FMJ ammo produces approximately 3,240 feet per second from a 20-inch test barrel. Specifically, velocity runs somewhat lower from a shorter 16-inch AR-15 barrel. Therefore, shooters should chronograph their own rifle for exact data. Always review safe handling guidance from the National Shooting Sports Foundation before heading to the range.

How should I store this Magtech 55gr range ammo?

Magtech 55 grain FMJ ammo should be stored in a cool, dry place away from direct sunlight. In addition, keeping ammo sealed in its original packaging prevents moisture exposure. Therefore, a sealed container or ammo can adds extra protection long term. Proper storage preserves reliable ignition for years.
