ZSR's 5.56mm load takes standard M193 specs and kicks them up a notch. Launching 55-grain pills at a scorching 3240 fps, this round outpaces typical commercial offerings by a healthy margin. That extra zip translates to flatter trajectories inside 200 yards, where most practical shooting happens. If you're looking to maximize your AR's potential without breaking the bank, these rounds deserve a serious look.

Beyond paper-punching, this ammunition really finds its stride in practical applications. That increased velocity creates devastating results on prairie dogs and other varmints, while still keeping costs reasonable enough for high-volume shooting. The standard 55-grain projectile weight means your existing zero stays true, whether you're running a pencil barrel or a heavy profile tube. It's particularly effective in carbine-length gas systems, where that extra pressure helps ensure reliable cycling.

For shooters building their skills, this load offers an ideal balance of performance and practicality. The minimal recoil lets you hammer rapid follow-up shots during drills, while the consistent velocity helps build reliable holdovers for stretching your range. Unlike boutique offerings that cost too much for regular practice, these rounds let you train hard without second-guessing the ammunition budget. Load up a few magazines, and you'll quickly understand why experienced shooters keep coming back to straightforward 55-grain loads for serious training.
