Remington’s 7mm Mag. came on the scene and won the hearts of many hunters looking to use a bullet of less than .30 caliber, and quickly overtook the .264 Win. Mag., forcing it into near-obscurity. And, in spite of the myriad attempts to produce a 7mm Mag. that will better the performance of the Remington version, it still maintains its seat at the head of table.
While there are many classic wheelgun calibers that date back to the late 19th century—the .44-40 and .45 Colt foremost among them—the relatively modern .44 Rem. Mag. has a well-deserved place among the most effective developments for a revolver, and will undoubtedly remain there for our lifetime and beyond.
