I'm a big fan of 2000mr for 223! Drops well, consistent, packs in tight. I use it with the 75 eld. I found ar comp did better with the rdf though.I tend to color outside of the box.
69gr SMK & TMK or 70gr Nosler RDF over a charge of Alliant PP2000MR .
This for my wife's Savage 110FP in 223 Rem 1:9.
52-55 with 23.5-25g h335. Every bolt gun I've started with this has produced under an inch with some combo in there. For a savage factory barrel, that's good. Fine tune with seating depth. Same thing you do for any rifle.
Or, if you are just wondering if it's a shooter, grab some factory ammo like the 53 Vmax and head to the range
