try 45grs of RL-19, all of my 243's (11 of them) will shoot that load, it's my go to load. Shot a lot of bug hole groups with that load. Killed a lot of deer with that load. Gave my friend 10 of them to try out of his Savage 11 and he called me up and said he shot a 3/8" hole group at 100 yards with them.
