I have a Savage 12FV .223 with a 26" 1:9 barrel. Right now I am loading Hornady 75gr BTHP over 23.5gr of Varget, Rem cases CCI 400's with a COL of 2.250". They shoot great out of my rifle, however I now want to play with the COL.

After using the RCBS Precision Mic to measure to the lands then backing off .010" I get a COL of 2.400" which is .140" over the max of 2.260" as recommended by the Hornady manual. I've never loaded longer than a published COL, so this is new territory for me. I've loaded up some dummy rounds (no powder or primer) at 2.400" and they feed and chamber in my rifle so no problem there.

Just wondering if anyone loads something similar.

Using the RCBS P/M, I found that my current COL has the bullet .155" from the lands.
