While most tactical rifles and shooters today rely on the .308 Winchester cartridge, there are those who reach for a .300 Winchester Magnum, and for good reason. It's a great mid-ground performer, providing a good deal more reach than a .308 without the disadvantages of the big .338 Lapua and .50 BMG.
There are several top-notch match-grade .300 Winchester Magnum factory loads available--three with 190-grain hollowpoint boattails and one utilizing Hornady 's polymer-tipped 178-grain A-Max.
A 190-grain bullet exiting at the velocities provided by the .300 offer a significantly flatter trajectory and less wind drift than a 168-grain bullet from a .308. I've shot distant steel silhouettes with a .308 side by side with a .300 chambering 190s. The difference is worth experiencing.
