If I remember correctly I used the 20-223 file as well. Make sure you get the correct information regarding your fired case into quickload like the trim length, Water volume. Input the correct conditions also. Quickload is very helpful in developing loads but there is a learning curve and you have to true the program with your real world data. Then I find a load that fits my OBT and where the Z1 and Pmax are very close or right on top of each other. And for some reason I have had good luck on the 3.5 node. Send me a message or an email if you have any questions I will PM you my email.
In my 20 practical I use Ar comp, IMR 3031, N133, Varget, ect. I use AR comp and 3031 the most. I use 40 grain BIB's and 35 and 40 grain Berger's. Good Luck, Randy
