Yes I actually tried this.  Infact it turned out to be alot of fun.
So here's the details.  The gear is your basic DPMS M4 -.22 kit.
100 yards = 4 on the rectical
300 yards = 7
400 yards = 8 the last line with hold over of about 4mm.

With ammo prices going into space I thought I would just "try" it out and see what the acog would do for me.  So basically I have almost a 3 grand .22 lol.  Rifle with "extra" parts around a grand.  Can = AAC-2000 mod-07 and then the acog is another 2000 or so.

Ammo used was Dyna Points value pack.  Was ALOT of fun hitting steel that far out.

ETA Re-ranging on the recital.

Have fun
