The .26 Nosler is a great cartridge. The idea if you purchase a more mundane cartridge you will practice more is ridiculous if you like to shoot. I wore out a .7-300 Weatherby and rebarreled it to a 7-8mm Rem Mag. When that wore out I rebarreled it to a .375-.416 Rem Mag and purchased another rifle and made a short fat seven.
Buy what you want and go play.
