Ballistics vs Barrel Length

[TANGO2072]

Wondering if anyone has a good lead on where to read up on Ballistics vs Barrel Length.

I am looking to convert my AR10 from 20" to 16".

( honeslty cause I dont have access to a Range with more then 110yrds at best to shoot at ).

So Im looking for more of a "Battle Rifle". I am curisous as how a 16", 18" measure up to

distance out of a 20". Using either 147 or 168g.

There's quite a few ballistic calculators available. I started a collection of info here. Maybe something there will help.

Heres some stuff i bookmarked a while ago

Your going to find that 16" is just fine  :)
