Prvi makes ammo and brass in a great many cartridges. If you can find it, it is as consistent as Lapua and less money than Winchester. Even buying loaded ammo, the price works out about the same as buying brass and you get a free round of gopher or target shooting out of it.
I tend to use a lot of Rem and Wincheter just because it is eay to get, cheap and pretty good quality. For my high volume guns, where I am buying 2 or 3000 cases for one gun, price and availabiltiy makes a big difference.
