Remington's reputation aside.
The best shooting 7mm that you can buy, is the one that fits YOU the best.
Go to a gun store and handle several, from as many different manufacturers as they have available. I have a Ruger, and love it. My father shoots a Browning BAR, it doesn't fit me as well and my accuracy with it shows. DO NOT restrict yourself to certain makers.
Buy a QUALITY scope.
The 7mm will out shoot you, with a good gun and scope combo.
