LoL, if you're scope is centered correctly, you might as well not even be shooting that day if you run out of windage adjustment! That's me anyway.
Tikka accuracy is well known. What's impressive is that the OEM plastic stock does not detract from that, and it sounds like little to no load development was done before this outing.
It seems like many of the off the shelf bolts under $1K are capable of well under 1 MOA these days; Howa, Wby Vanguard, Browning, Tikka, Savage to name a few. You don't NEED to spend $2K to get < .5MOA if you reload. But of course, more expensive toys are usually cooler and better in some way.
