The 7 mag has a great reputation, is easy to shoot, and the reason it’s become so popular out west is simply because it works so well. 7 mag and 160 gr Partitions have worked so well “upgrading” to something else for 500 yard shots is like buying a new mousetrap - buy it if you want, but there’s nothing wrong with the old reliable. I’ve shot 160 gr monos and got plenty of penetration, but small hole and slow results. Accubonds are also good, but I’m happy as a clam with Partitions.
I picked up a 6.5 PRC to replace the 7 mag I’ve used since the 1990s - to get with the times, modernize, and all that. The more I shot it the more it sunk in, it’s duplicating 270 win performance, not equaling the 7 mag. I’m happily back with the 7 mag.
It takes a big commitment of time and money to do serious hunting, and a second rifle is always a good idea. Every year we have guys panicked because something about their only rifle isn’t right and the season is only days away.
