Re: 7MMremmag. Berger vs Matchking?
Just my opinion, and I know with some calibers we have no choice, but Remington is the last brass I would use. I loaded it for 10 years then went to Winchester. In the last 5 years I've used Norma, WW, Lapua, and Federal in my various calibers. I'm on a batch of 500 Nosler 7mm Rem Mag currently. It does well.
