I don't hand load, gonna try some 95 gr. Federal Fusion next trip to the rangeNice rifle, it should shoot well.
Do you hand load? If so, try the 95 grain Nosler ballistic tips or 85 grain Sierra hpbt. If you don’t hand load then try to find some factory stuff with ballistic tips or Vmaxs.

Best I can measure is is 1/10 twist. Bought some Hornady Precision Hunter 90 gr. ELDX. Gonna try these. Hope they shoot good.Coopers are sweet! Have you checked your barrel twist? I don't know if the varminter models have slower twists or not, but if it does, your decision to go with a lighter bullet should pay off
