Reloading suggestions

[Spj0487]

Hello everyone this is my first post. I am trying to get some references since I’m about to start reloading my 6arc. Currently running a AR15 with a Faxon 20 inch barrel shooting hornady factory loads 108 ELD-M. These are the chronograph velocities and information I have for this round using a magneto chronograph. My question is is this a higher than normal velocity for my set up and if not what other most closely mimics the factory powder used by Hornady. I have already taken down a pig at 645 yards with this set up and like to keep it if possible.Thanks
