Seeking advice/opinions on 300 win mag for first long range gun

[FIGJAM]

Shot my new x bolt hells canyon long range yesterday. Took me 3 shots to zero it. The next 7 shots went into sub MOA at 200 yards. That was just a random handload with some H1000 and 175gr MatchKings. After that I'm kind of expecting to see this rifle shoot .5-.75 MOA with good handloads.

I think x-bolts are where its at right now for a factory rifle. I have a medalion that is gorgeous, but I am planning on getting a long range mcmillan here shortly. Every x-bolt I have shot (7 of them) have been great shooters.
