Curious if anyone has any experience with 556 out of a barrel under 10in? I do not have a truck gun and leaning more towards the 556 PDW realm. I plan on going to a different system then an AR as DI seems to get finicky when dropped below this length. Not to get too deep into the caliber debate but just curious if anyone as any personal experience to speak on.
My thoughts: The bullet is still going over 2300-2200fps out to 100m, I want the bullet to be effective out to 100m (more than likely closer), SP ammo will mushroom out (vers tumble or break apart of fmj), its definitely more effective then 9mm at these ranges. Also I like the logistics of a platform that will take STANAG/ PMAGS and 556 chambering (If someone needs to throw me a mag or I pick one up I can stay in the game)
The Cons are obviously muzzle flash/blast. And obviously more velocity is better for the cartridge.
