Ishootkittens - I was about to buy a 300wsm abolt last week ($450 used) but it sold before I got there. I have 338 xbolt love it and might save my pennies and get the 300wsm in xbolt, for better and worse I like Brownings.
I am a little surprised no one has knowledge of this conversion. I see that browning is chambering a 26 nosler now in a couple xbolts so hopefully down the road 30 nosler will come to stores near me. Then a barrel swap would be less of a hassle for acquiring components, I think I will keep looking then
