69gr is a bit heavy for 1.9 twist. 62gr will work better.I stay with 55gr Hornady FMJBT. Cannot remember the powder charge and am not at home right now.
I reload using a Dillon 550B and/or a Lee Classic turrett. It is not practical to use a progressive press with a bottle neck cartridge that is being loaded for use in an AR platform as the case needs to be full length resized and then trimmed, etc, etc before dropping powder, seating, and crimping.
I also find that I can buy 55gr FMJ ammo by the case for about 5 cents per round more than it cost me to reload it. Don't know why I continue to reload that caliber.
