I bought a .300 Weatherby Vanguard, made by Howa, about 5 years ago. I'm getting sub-moa groups with both 168gr and 180gr Barnes TSX bullets, and almost half moa groups with 168 gr Barnes TTSX bullets. It also shoots several types of Cup and core bullets very well, and 160 gr cast bullets well enough for very cheap practice.
I've used it on hunts in Texas, Montana, and South Africa, and it is one of my favorite rifles.
