264 Winchester Magnum History And General Information:
Written by: Kim Lockhart, Copyright.

264 Winchester Magnum:
 The .264 Winchester Magnum was one of a series of short belted magnums developed by winchester, it was officially introduced to the public in 1959 by winchester.

 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 3100 fps. it is a very adequate round for deer at 500 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.

 The 264 winchester magnum when loaded with 129 grain bullets recoil is quite minimal and controllable when loaded with 140 grain bullets the recoil increases quite a bit, a good recoil pad fitted to the rifle will tame the recoil before it gets to your shoulder.
