The AR-15 platform, chambered in .223 Rem./5.56 NATO, is the most popular of all modern rifles in America. While there are a plethora of options out there for advanced hunting ammo, superior match-grade loads and lethal self-defense rounds, most people opt to practice with inexpensive full metal jacket rounds.
These are classic, reliable loads that are designed to give good general performance on a budget. Today the Sig Sauer 55-grain Elite Ball FMJ goes up against the Hornady Frontier 55-grain FMJ M193 to see who comes out on top.

Practice ammo of the 55-grain variant has been the training standard for the AR-15 platform for the last half-century. This ammunition offers decent velocity and accuracy while keeping material cost down – a bonus for penny-pinching shooters.
The M193 load by Hornady is essentially a duplicate of the original M193 round that was adopted for military service in the 1960s. Sig Sauer’s 55-grain full metal jacket is not so much a duplicate of any military load but is instead a modern commercial grade practice option for bulk
