I have the same gun, but in stainless synthetic.
Winchester WLRM Primers
Scary Accurate, shoots 1/4"... I get alot of same hole performance too..
Nosler: bullets, ammunition, rifles, brass, and reloading data.
Just tried this load today:
Winchester WLRM primers
115gr Sierra Matchking
Shooting a little less than 1/2" right now with the 68gr charge. Load seemed to want to go faster. Group tightned up when I went from 66gr to 68gr. I'm going to try another 1/2gr incriment and see what it will do from there.. Both loads are impacting within a 1/2 inch from each other... This means I can shoot both bullets with moving a thing.
Can't wait to try the 110gr TSX:

My Tikka sits below a Zeiss Conquest 4.5-14x44mm scope... Rock Solid!
