The .243 Winchester has a larger case capacity than the .223 Remington, which allows it to hold more powder and generate higher velocities. This also contributes to the .243's superior performance at longer ranges.
Bullet size is also an important difference between 223 and 243 ammo. The .243 Winchester has more recoil than the .223 Remington due to its larger bullet and higher powder charge. This can be a factor to consider for shooters who are sensitive to recoil.
The cost of both calibers can vary depending on several factors, including the brand, quality, bullet type, and quantity purchased. On average, you can expect to find .223 ammo priced starting at $0.40 per round, While the starting price per round for .243 Winchester is more than twice that of .223 Remington.
The .223 Remington is more widely available and generally less expensive than the .243 Winchester. This is because the .223 is used in a popular platform like the AR-15, which has driven up demand for both the cartridge and related components.
Remember, there's no one-size-fits-all answer. Consider your preferred game, shooting style, and recoil tolerance before making your pick. Both cartridges are capable companions, so choose the one that speaks to your inner hunter and lets you face the season with confidence.
And remember, at the end of the day, the most important shot is the one you put between the sights, not the one you have in your rifle. So practice, sharpen your skills, and make every shot count, regardless of the caliber you choose.
Happy hunting, partner!
