If you can replicate the muzzle velocity and pressure curve then sure, start at factory OAL. I haven't had much success with this tactic, however.

Now you are past my learning curve. I don't even have a chronograph yet. My plan was to start low and just slowly increase charge trying for accuracy. I'm more concerned about a good consistent grouping than chasing an extra 100 FPS. I might be wrong but I don't really see that it will much matter since 300 yards would be a really long shot for 99% of my hunting. The last 50 deer I've killed have been under 100 yards,but I still love shooting tiny groups as far as my home range allows,just over 250 yards.
