This round features a tried and true 55 grain FMJ. That’s the standard weight which any rifle enthusiast worth their salt is accustomed to, and the standard bullet you want for reliable feeding, a cleaner barrel, and predictable ballistic performance after every shot. The FMJ isn’t designed to fan out and do more damage inside of a living target, but it’s not precisely the best thing that could happen to a living target, either. This round’s 3,240 fps muzzle velocity is only 10 fps slower than the Army’s M193 ball load!
That’s not a manufacturing defect you’re seeing on this round’s new brass shell casing. It was made by the Lake City Army Ammunition Plant, which means its neck is heat-treated to promote superior suppleness for cleaner ignition and repeated reloadability. Frontier loads also feature military grade primers and propellant, so they’re a picture of reliability! (Handloaders take note that those are indeed crimped primers.)
