thank you for this, does anyone know if there is a 300blk 220gr sub sonic chart out there somewhere?

I'm sure if you do a reverse image search you'll find different charts.

great idea, did find a set for 556 but no 30025, 36, 50,100

Been trying to find something like that for 9mm carbines

The effective range of a 9mm carbine is substantially less than a 556 or 223. I don't know if it even warrants chart like this one. I certainly wouldn't be utilizing it beyond 50-75 yards. 3 to 3.5 MOA at 100 yards with a 16 inch barrel leaves a lot to be desired.

They're more accurate than you might think at 100 yards. Depends on the round. Sweet spot for mine is 124 grain, although 145 can be pretty damn accurate too. The full burn in a 16 inch barrel gives much different long range ballistics than out of a 4 or less.

But you are right, a 556 is gonna be the superior rifle for long range engagements, assuming that's what you want out of your weapon. my carbine is better for my use-case

Ah I see. I prefer 300 blackout subs suppressed for what I'm guessing is your use case. Are you running suppressed?
