Loads for 300 WSM? M70 Extreme Weather

[ktsmith29]

I recently picked up a Winchester M70 Extreme Weather chambered in 300 WSM, manufactured in 2017, but looks almost new. It appears very lightly used, put a bore scope down it, threading all looks fine, no issues to note and it was a good deal so I bought it. Grabbed 3 different boxes of ammo from sportsman's, all Federals, 165 gr, 180gr, and 200 gr. Long story short they all shot terrible, like 3"+ at 100 yds. I have quite a few 212 ELDX's and 210 VLD's and both IMR 4350 an H4350. Anyone have some loads that they use or have experience with accuracy issues in the M70 300 WSM? If you load the 210 VLD's what COAL are you guys at so I can have a rough idea where I should start. Thanks in advance.
