I am fairly certain that 300 WSM was announced by Q as a caliber they were going to offer for the Fix. Here is a TFB article, but I don't really know of an official statement: https://www.thefirearmblog.com/blog/2017/01/31/q-hq-fix/just passing through. is the WSM bolt/mag going to happen, or just SH rumor?
My guess is that Q is really preoccupied with creating their new hotness, the 8.6 Creedmoor, and we'll likely see that released before 300 WSM. It has been hard enough to find any of the current offering's barrels, and the barrel nut wrench has been out of stock for weeks if not months at this point. At the same time they also have irons in the fire for the Mini Fix, an R700 Fix chassis, a bipod, and suppressors, it's hard to see how soon we'll see more love for their fullsize Fix.
This is 100% my armchair speculation though, from following them on social media and being generally interested in the company as a whole. I could be completely wrong.
