264 Winchester Magnum / History:
Centerfire Rifle Cartridges
Written by: Kim Lockhart, Copyright.

264 Winchester Magnum:
 The .264 Winchester Magnum was one of a series of short belted magnum rifle cartridges developed by Winchester, it was officially introduced to the public in 1959 by Winchester featured in their model 70 Westerner bolt action rifle. Today the 264 Winchester Magnum cartridge is chambered in their model 70 sporter that features a 26 inch barrel to extract the high bullet velocity this cartridge offers.

 The 264 Winchester Magnum is an excellent, accurate, and flat shooting cartridge that is capable of taking any game in the lower 48 states and is one of the more powerful .26" caliber cartridges, when loaded with 140 grain bullets at 3,000 fps. it is a very adequate round for elk at 300 yards.

 The 264 Winchester Magnum has had a reputation as being hard on barrels and will wear out in as few as 500 rounds, back in 1959 this may have been true but we are now into the 21st. century where cryo treating barrels extends the life of barrels considerably and this would include the 264 Win. Mag. as well. If the barrel is allowed to cool between shots barrel life can be into the thousands of rounds fired before concern of this happening.

 The 264 Winchester Magnum when loaded with 120 grain bullets, recoil is quite minimal and controllable and offers a very flat bullet trajectory quite comparable to the 257 Weatherby Magnum. Nosler ammunition offers a wide selection of excellent 264 Winchester Magnum ammunition today for hunting use. Their 140 grain bullet loading is with their partition bullet which insures deep penetration on larger deer species. Their 100 grain bullet loading has a good ballistic coefficient for laser like precision out to about 225 yards for predator hunters using the 264 Winchester Magnum.

 To achieve maximum accuracy from your 264 Winchester Magnum rifle there are several things you need to do correctly that will help increase your rifles overall accuracy capabilities.
First: Properly mount your riflescope.
Second: Properly break-in your rifle barrel.
Third: Properly sight-in your rifle.
Fourth: Properly clean your rifles bore.
 To accurately calculate ballistics for your rifle with ballistics programs you need to measure your rifles scope mounted height.
