First, I assume you are shooting an AR since you are looking at the 223 series of scopes. Whichever one you get, be sure to use the free Nikon Spot On software with it. It will match any load you shoot at any power and give you range cards you can print out. There is also a Spot On app.
The P-223 series is the best bang for the buck. The new PROSTAFF 5 series is a major upgrade in quality. The M-223 is MONARCH glass and coatings=excellent. I have shot both the P-223 and M-223 out 500 yards with the Spot On data.
I personally would go with the regular BDC reticles. Nikon has 11 of them for different purposes.
If you want an AR scope look at the SWFA deal on the P-223 4-12x40 with the SWFA one piece mount for $270.
The M-233 3-12x42 with the same mount runs $480.
