.264 Winchester Magnum - Background

Background

The .264 Win. Mag., like many magnum rounds, can wear out barrels more quickly than other rounds. This was particularly true in the 1950s to early 1960s, with the chrome moly steels then almost universally used for barrels. But recent advances with stainless steel barrels, especially when cryogenically treated, have extended barrel life considerably, with the .264 Win. Mag. and many other cartridges.

While very few production line riflemakers currently offer the .264 Win. Mag. as a factory chambering, the caliber remains popular with some enthusiasts using custom built rifles and handloading their own ammunition.

The introduction of Remington's 7 mm Magnum in 1962 almost immediately eclipsed the .264 Win. Mag., even though the 264 Win. Mag. uses an identical brass cartridge case (the neck diameter of either cartridge case can easily be modified to accept the others' bullets by the handloader), it never fully recovered from the competition of the slightly larger-bore cartridge.

The fact that the 7 mm Rem. Mag. thoroughly eclipsed its popularity has been attributed to many causes, the premature "burning out" of barrels as compared to the Remington cartridge often cited. More likely is the fact that hunters had more confidence in the game-getting ability of heavier 7 mm (.284") 150 to 175 grain spitzer-shaped projectiles on big game, as compared to 140 grains being the upper end of pointed .264 bullets.

Conversely, Winchester marketed the .264 as a long range, combination varmint and deer round, although suited for harvesting the occasional elk or moose. Unfortunately, the recoil it generates, plus the expense of the sheer quantity of ammo that may be used to shoot pests at long range (compared to pure varmint cartridges like the .222 Remington and the .220 Swift, or the smaller varmint / deer rounds, like the .243 Winchester) inhibited its popularity further. The result was more sportsmen opting for the bigger Remington 7 mm round because it was seen as more effective on wider variety of big game; rather than a compromise round that could be used for varmints, worked well on whitetail and mule deer, but was borderline for the largest North American big game should the need arise.

In Europe, two of the .264 Win. Mag.'s champions were George Swenson of John Wilkes gunmakers, London, and David Lloyd of Northampton, England. Lloyd built a number of his deluxe Lloyd rifles in .264 Win. Mag. calibre, mainly for sportsmen seeking a calibre that would give high velocity performance with bullets heavier than the 100 grains fired by the .244 H&H Magnum.

Famous quotes containing the word background:

    Pilate with his question “What is truth?” is gladly trotted out these days as an advocate of Christ, so as to arouse the suspicion that everything known and knowable is an illusion and to erect the cross upon that gruesome background of the impossibility of knowledge.
    Friedrich Nietzsche (1844–1900)

    ... every experience in life enriches one’s background and should teach valuable lessons.
    Mary Barnett Gilson (1877–?)

    They were more than hostile. In the first place, I was a south Georgian and I was looked upon as a fiscal conservative, and the Atlanta newspapers quite erroneously, because they didn’t know anything about me or my background here in Plains, decided that I was also a racial conservative.
    Jimmy Carter (James Earl Carter, Jr.)
