This is what I’ve learned (in the event you didn't know these things):
The bullet 'weight' (length really) matching the barrel twist rate is an important factor for accuracy. Even though the exterior cartridge dimensions are almost the same, heavy bullets (69 gr.) go in high twist rate barrels (1:8"), light bullets (55 gr.) go it slow twist rate (1:12") barrels.
Oh, and while they look almost exactly alike, even though you can fire a .223 round in a 5.56 semi auto, firing a ‘higher pressure’ 5.56 round in a .223 rifle fatigues the chamber and one shouldn’t do it.
But that's not what you asked.
