The military began providing the lead-free round last June to U.S. soldiers in Afghanistan. It replaces ammunition used since the early 1980s.

A live-fire demonstration will be held Wednesday morning at the post. Soldiers will fire the new and old rounds, as well as a third type, to compare the performance of all three on identical targets. The targets will include a parked vehicle, steel plates and building materials.

The Army says the new ammunition is the first developed as part of a “greening”’ effort for small-caliber ammunition.
