7mm SAUM not really a magnum, more like a 280AI in a short action. Rifles are cheap, cases are plentiful, remington, Norma, and Nosler and 7mm bullets have great BC for long range, with tons of em out there. Mine is a model 7 stainless/synthetic, 22 inch barrel and it cost around 550 dollars. Dont believe what some say about the short/fat rounds, they feed slick as snot.

Im also a big fan of the 6.5X55, in a modern rifle its right on the heels of the .270win, which if you dont reload is the way to go, lots of good cartirdges out there that a flat shooting low recoiling...
