I have had good accuracy with 86-90gr of RL25 and the 220MK's with 89 being the most accurate with the bullet just off thwe lands. The gun did not shoot well off the lands when new (below 100rds) but now iseally accurate that way. At 90gr I would occasionally get a pressure signs depending on outside temp. (routinally gets 100 here). At 91 definate pressure signs (imprint extractor marks,tough to open, no mas). The 89gr load averaged 3013fps on a 10-shot string. This is all through a factory Sendero SF barrel
