Current Rifle Cartridges
.243 Winchester
The .243 Winchester was introduced in 1955 by Winchester for their model 70 bolt-action rifle.
The .243 Winchester is basically a .308 Winchester case necked down to accept 6mm projectiles.
This was a very successful caliber as Winchester had the foresight to use a tight 1 in 10 twist in the Model 70
barrel to stabilize heavier projectiles up to 100 grain, making this a great "all in one" hunting cartridge from
varmint to deer. Still a good pick today for the one rifle home.
Not to be confused with the .243 WSSM (Winchester Super Short Magnum)
