I have bought three used MK VWhat I had come up with originally was my best bet for a factory sub moa rifle would likely be the savage 111 LR in 300 wm or the browning hells canyon LR in 300 RUM - another interesting option maybe the 300 wby in a range certified vangaurd
That comes in around 900 with shipping and would be sub moa. It only has a 24 inch barrel though
1. 300 WBY, shoots 200 AB, 3 holes touching at 100 yards
2. 300 WBY, shoots 180 TSX, .432" at 200 yards
3. 338 LM, shoots 300 AB, .5" at 100 yards. Just started load development
