I had one with a 28 inch barrel. Shot the 175 grain Rem core lokt at 3400 fps.A throwback to 1986, Layne Simpson and Shooting Times Magazine. 7mm Magnum STW (Shooting Times Westerner. Based on the 8mm Remington cartridge. Very flat shooting and lots of energy. You already have so many great cartridges mentioned, as well as the 300 Weatherby. Just thought I'd throw another great one your way.
