IMI SS109 Bulk Ammo FAQs

What twist rate works best with this ammo?

IMI M855 62 grain ammo can loads need a 1:9 or faster twist rate to stabilize properly. Specifically, a 1:7 twist is the traditional military standard for this bullet weight. Slower twists like 1:12 may not stabilize this heavier bullet well. 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, IMI M855 62 grain ammo can loads are built to 5.56x45mm NATO specifications and are 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, since chamber pressures differ. Always verify your barrel markings first.

Does this ammo use reloadable brass?

IMI M855 62 grain ammo can loads use boxer-primed brass cases that are fully reloadable. As a result, handloaders can recover and reuse spent cases after firing.

How should I store this ammo can long term?

IMI M855 62 grain ammo can loads are already sealed for long-term storage in a cool, dry place. In addition, keeping the can unopened until needed preserves the factory moisture seal.
