Sounds good, thanks for the replies! Didn't know that about Shilen. A bit pricier, but I'm guessing the cost is worth it.

I also did some more digging and found out that the 28 nosler (and all of the nosler cartridges for that matter) are the same bolt face and same OAL as the 300 win mag. So, basically, go buy a 300 win mag, rebarrel, and I should be good to go.
