To answer the OPs question, mathematically there is a recoil difference of roughly like 10% between 130 and 150gr factory loads. In practice I don’t recall ever noticing the difference.
I don’t know what type of hunting you’re doing, but if it’s mostly stand hunting, I would consider a Boyd’s laminate stock, just because the weight will reduce recoil some. Also since there’s about a million Tikka’s out there you could probably sell it later for minimal loss if you wanted
