to see .9 go to 2+ ,
id guess something more severe than bullet choice
sounds like shooter error in parallax adjustment or loose optics
or
brake install ?? , still need even gap bullet clearance . bullet doesn't have to contact the new brake to open up groups
or
reloading consistency , i might suggest dry graphite lube with your last 24 as it could be a tension issue, 3 seated at max mag , 3 seated at minimum depth in case and 3 in the middle somewhere
( look at the drawing for your chamber , what angle does your drawing say at the "transistion to land" measurement )
