    I would test that load in different temperatures to see if you get more pressure. I would also drop the charge by .5 and see if you have the accuracy and lose the sticky bolt lift. I shoot a 208 Amax in my 300wsm with 4831sc at 2700 and it is crazy accurate.

    Wouldn't shoot a 200gr bullet out of a wsm. 180gr is where it's at 96% of the time for this cartridge. Big long bullets are somewhat of a nemesis for the short mags.
    I'd reduce the charge and find the low node.

    I shoot the 200gr ELDX in my Sako 75 300 WSM. So, my load should be very similar to what you would get in your Tikka. It was devastating on a NM bull elk this past October. Ragged 5 shot hole at 100 yards
    62.8 gr RL 17, COAL 2.855", 2952 fps. Nosler brass, WLRM primer

    I run the 200-20x berger in mine, the same 66.5gr of 4831 (not sc). Runs at 2826fps from a 24" barrel, no pressure signs.

    If your primers look fine, check case head expansion (are your primer pockets tight after a couple loadings?), and no case head swipes. At the temp you are shooting you are likely fine pressure wise. Your action could always have an issue with primary extraction, does it have the same stick feeling with a 64gr load?
