6mm Remington (244 Remington)
The 6mm Remington is based on the 7x57mm case necked down to .243 caliber and the shoulder angle increased by about 6 degrees.
Remington introduced this cartridge first in 1955 under a different name, the 244 Remington. In 1963 Remington reintroduced this cartridge as the now popular 6mm Remington.
The 6mm Remington never caught on in 1955 as it was introduced in Remington’s model 722 varmint rifle with a 1 in 12″ twist barrel, while this gave excellent accuracy and ballistics with lighter bullets in the 70 grain weight range it did not stabilize heavier bullets in the 90 – 100 grain weight range.
Remington dropped the 244 Remington and reintroduced it in 1963 as the 6mm Remington chambered in a Model 700 rifle with a 1 in 9″ twist rate in the barrel.
The change in twist rate added the versatility that was needed and heavier bullets would now stabilize.
Any decent rifle will need a good scope. Check out this one from Bushnell.
It is a good dual purpose cartridge. When loaded with lighter bullets it is extremely effective on varmints able to send a 75 grain bullet out of the barrel with a velocity of 3,500 fps. The ballistics are excellent out to the 400 yard mark.
When loaded with 90 grain bullets at 3,300 fps, you have an excellent deer and antelope round good for 300 yards.
The 6mm Remington is a moderate recoiling round which is comfortable enough for almost anyone to shoot.
For a beginner just getting into the high power rifle sports the 6mm Remington cartridge has a lot to offer in ballistics and light recoil and is highly recommended.
Also for anyone that is recoil sensitive this is a great cartridge.
