One of my closest pals is in the business of building high performance BG hunting rifles. They aren’t cheap. The Proof CF barrels outperform all others. He delivers each rifle with ammo developed for that rifle.
His rifles in 28 Nosler, 300 PRC, 338 Lapua, and such cartridges average in the .300’s with full-on hunting loads. He has done at least 50 in the last few years so his results are based on a good sized sample.
