Looks a lot like what I got with the same powder/bullet combo in my EW... IMR 7828 brought me considerable consistency with the 120TSX / 127LRX. . Fortunately I have 6+ lbs of my 8lb keg of Retumbo. Found it to deliver consistent sub 1/2" groups with the 140gr class C&C bullets, but the Barnes mono even though lighter gives consistent 100% penetration on elk.
