M855 is the Nickelback of 5.56mm rounds. Everyone likes to tear it down.
In my rifle, with a 1:7 twist barrel, Federal M855 groups better than Federal M193 at 200 yards. IMI 77g match does (unsurprisingly) better than both.
I like M855 as a “do everything” round, that’s cheap enough to plink, plus accurate and effective enough against people and armor.
Nickelback of 5.56 rounds. lol... i like that.
good sumamry... M193 is hit or miss with a 1:7 twist... same will do okay... most will be `4 MOA or even worse. out of 1:8 or 1:9 M193 will outperform m855 from an accuracy standpoint.
but agree with your assessment... M855 is the ‘do all’ round... jack or all trades, master of none.
