243 Winchester / Rifles / Twist Effects:
Written by: Kim Lockhart, Copyright.

The popular .243 Winchesters in most rifle configurations are well known for their accuracy, this is partially due to the fact that little recoil is felt by the shooter therefore reducing recoil flinch when shooting. Bolt action 243 Winchester rifles are very popular for hunting and target shooting. Compared to most other manually-operated firearm actions, they offer an excellent balance of strength, simplicity, and potential accuracy. The major disadvantage is a slightly lower practical rate of fire than other alternatives, but this is not a critical factor in many types of hunting and target shooting.

 .243 Winchester rifles are light recoiling and comfortable enough for anyone to shoot accurately. For a beginning rifle hunter just getting into the high power rifle hunting sports, the .243 Winchester is highly recommended. Also for anyone that is recoil sensitive this is a great rifle and cartridge combination.

Varmint Rifle:
The .243 Winchester rifle chambering is an excellent choice for varmint hunting as it is a powerful varmint cartridge and one that I consider as a long range varmint cartridge. The .243 offers plenty with low recoil, low noise and at a high power flat bullet trajectory level. The .243 is very popular for varminting and predator hunting because it offers a tremendous variety of loads, bullet weights and plenty of loading data. The heavier .243" bullet does better in the wind than any smaller caliber. I have used the 87 grain bullet weight in my own personal rifle as a deer round and as a favorite long range varmint round for years.
Recommended barrel twist rate: 1 In 10".

 A too-high rate of twist can cause problems with light-weight bullet use in the .243 Winchester. The excessive twist can cause accelerated barrel wear, and in high velocity bullets an excessive twist can cause bullets to literally tear themselves apart under the centrifugal force before reaching their target down-range.

Deer Rifle:
The .243 Winchester rifle chambering is an excellent choice for deer hunting. I have used this round on many, many deer hunts where I knew the shots would be under 300 yards. The two bullets that I load exclusively for my own .243 are the 87 grain flat based bullet made by Hornady and the 100 grain flat based Remington Core-Lokt bullet, in my 26 inch 1 in 10" twist barreled, 98 Mauser, bolt action rifle these bullets are extremely accurate and bullet expansion is excellent. The 87 grain bullet gets used for all doe hunting and deer in general that I know for the most part will be under 150 pounds in weight. The 100 grain bullet gets used when I know for sure that most shots will be long and or windy days, also when the deer could weigh over 150 pounds.
Recommended barrel twist rate: 1 In 9".

Note: How To Measure Rifling Twist Rate.

 When choosing a rifle cartridge you should always evaluate what you are going to use the rifle for and then select the rifle with the correct rifling twist rate for your imparticular use by bullet weight to gain the most accuracy and bullet expansion.

 A good rule of thumb is that the heavier and longer a bullet is, the faster the rifling twist rate needs to be to stabilize it in flight, therefore a lighter shorter bullet needs a slower rifling twist rate to give proper bullet spin for correct flight and expansion.
