Item #1: Bed and float your Classic, that'll put you into MOA right away.
Item #2: As someone has said, the .223 is really not a long range gun...yes you can hit stuff way out there, but you are looking for enough retained energy to kill stuff.
Item #3: also as someone said many good varmint bullets will get you to 500 yards in a 12 twist. 500 yards is farther than you think......handload 55 grain NBTs and rock on.
55 grain NBT has been my favorite coyote bullet out of a 22-250 for a long time.
Should be pretty good from the 223, only kilt 1 with said bullet in 223 so far and it was the usual DRT that I get from the 22-250.
The NBT 50 isn't far behind it though. Killed quite a few with that out of my last 250.
