Burnsy87:
I'm math dumb, so forgive me.  I have a few AR's I don't necessarily want to use for deer - coyotes are another matter - but I'd just like to know how to calculate that number we need to hit.

HuskerXDM:
Quick google search this one has a calculator

I know it's for air guns but plug in bullet weight and velocity

Burnsy87:
I don't know actual velocity out of different barrel lengths though.

jonm:
chrony is the right way or Google will get you close.

tstuart34:
Factory or reloaded ammo?
