Ballistics and practical applications

The 55Gr projectile is a common sweet spot in 223 Remington loads: lighter than heavyweight match bullets for faster cycling, yet heavy enough to retain energy and stability out to practical engagement ranges.

At a retail price of $39.99 per 20-round box, the LAPUA FULL METAL JACKET sits as a premium option for those who value consistency over bargain bulk buys. The compact 20-round packaging is convenient for range bags and controlled carry storage.

Handling and compatibility notes

When integrating any new ammo into a defensive or training regimen, verify feeding, extraction, and group performance in your specific rifle. Lapua rounds are well suited to duty-style magazines and magazines designed for reliable stacking; they also perform well in precision platforms for zero confirmation. Always adhere to safe storage and handling practices and consult your firearm’s manual regarding recommended ammunition types.
