What is 338-06?

The .338-06 is a wildcat cartridge based on the .30-06 Springfield case necked up to .338 caliber. It was popularized by gun writer and wildcatter Warren Page in the 1970s as a powerful yet versatile big game hunting cartridge. The .338-06 offers a good balance of power and trajectory for hunting a wide variety of game, including deer, elk, moose, and bear.

The .338-06 is capable of propelling a 200 grain bullet at velocities of around 2,800 feet per second, delivering excellent energy and penetration for taking down large game animals. The cartridge has moderate recoil, making it manageable for most shooters.

While the .338-06 is not as common as some other big game cartridges, it has developed a dedicated following among hunters who appreciate its versatility and performance. Handloading is often required to obtain ammunition for this wildcat cartridge, as it is not commonly available from commercial manufacturers.
