IMO its totally up to you
I have seen the consistency from factory rifles that you expect from a custom
there are plenty of rifles out there that would make a good range plinker
your choice of 223 is a good one because of barrel life but it wont shoot in wind, I would look at a 6mm
and this is what I would advise you you think about for what you are going to do,

what I would look at anyway
I would try and get the price down a bit though
