My Ipad I had hooked to the chrony is in my truck and my son borrowed it yesterday, he supposed to bring it back tonight.
But going from memory my numbers almost mimic yours, about 100 off of published dadta and about 200 to 250 off of factory rounds. I was loading 105 and 108 grain bullets. My thought was to throw out all previouse data and start over. I am going to work these two loads up to match the velocity of the factory round and stop there.
I think if you start just shy of the max Hornady data and work up you would have a good starting point. I am loading all my 6 ARC rounds with CCI 450 magnum primers, as others have had issues with flattening and cratering going above listed loads.
The way I see it Hornady is getting 2700 + out of their factory loads, but they only supply data to get you in the 2500 fps range, thats a pretty good spread.

If you can not see the tyranny of having a gun ban enforced by men with guns... Then you fail to understand why the second amendment was written in the first place.
