This is M193 ammo, made for civilians instead of folks who get screamed at for not following dress code. Each round sports a simple 55 grain FMJ bullet to promote uninterrupted feeding into a semi-automatic rifle’s chamber and reduced lead fouling of the barrel. Winchester’s consistent FMJ exhibits a G1 ballistic coefficient of 0.250. That keeps its velocity well above 2,000 fps at 300 yards, which promotes a flatter, more accurate trajectory.
Winchester’s jacket doesn’t contain any steel, so unlike Russian ammo you’re cleared to take these cartridges to any indoor range. Their nonmagnetic bullet stays seated at the correct depth in its case thanks to its toothed cannelure.
This non-corrosive ammo sports freshly minted brass cases. Winchester doesn’t polish this ammo’s brass cases after heat-treating them, so while they’re a little less pretty you can rest assured they’ll stay supple even after they’ve been fired a few times.
