I'm just starting my build but when it is done it will be a dedicated 9" with Trident9 and OAL 16.5" running 220gr @ 1050fps (that's what I'm calcing with for now at least) and looking for the perfect scope for 0-200 yards I found only (2) so far. One is the S&B short-dot which is $2400.00 and the other is not out yet but looks very promising.
I made a spreadsheet using random range and size to see which reticle would be best and found the mrad better than the MOA for this application.
The scope I'm getting is:

The spreadsheet using JBM calcs on the Ballistic iPhone app is on my website:
