.243

The 243 Winchester (aka 243 Win) was introduced during the 1950s as a medium and small game hunting cartridge, and remains exceptionally popular among American hunters to this day. If you’re taking aim at rodents or predators, consider using a lighter 58 grain polymer tipped bullet like the Hornady V-MAX (heavier 75+ grain V-MAX loads are also available for long-range varmint hunting). For deer, an 80+ grain soft point or Triple-Shock X (TSX) bullet is advisable.

Common 243 Winchester Ammo Questions

How Far Can You Accurately Shoot with a .243 Winchester?

Quite a distance! Trajectory, of course, depends on many factors, including bullet design, barrel length, and bullet weight, so all cartridges will perform differently. However, Winchester’s Varmint X with 55-grain hollow points when zeroed to 100 yards will only drop 1.7 inches at 200 and 7.7 inches at 300 yards, all while maintaining speeds over 2,000 feet per second. (The muzzle velocity for this round is 3,910 feet per second.)

Even larger bullets loaded into the .243 Winchester have excellent trajectories. Winchester’s 100-grain Power Max Bonded ammunition only drops 3.3 inches at 200 yards when zeroed to 100. At 300, it drops 12.2 inches. For the bullet size, these are excellent trajectories.

What is the Best .243 Winchester Bullet for Deer Hunting?

That’s a tough question, but you should always choose a round that has an expanding bullet for hunting of any type. You’ll want a jacketed hollow point or ballistic tip round to ensure proper expansion, which will result in a larger wound channel and a faster, more humane harvest. For deer, you’ll want something on the larger end of the scale, which for a .243 Winchester cartridge is about 90 to 100 grains. When properly placed, this bullet size can effectively drop a whitetail deer and many other medium-sized game animals. Check out this article if you're unfamiliar with the common bullet types deer hunters use.

What Firearms Shoot .243 Winchester ammo?

The .243 Winchester is a rifle cartridge, and the majority of firearms that load this round are bolt-action weapons. Bolt-action rifles are known for their accuracy and effectiveness, allowing you to place one shot exactly where you want it. You can find semi-automatic rifles that shoot the .243 Winchester, but they are relatively rare. If you're unsure, check your firearm near the barrel area. If it says it's chambered in "243 win" or "243 Winchester", this is the ammo you want.

How Does the .243 Winchester Compare to the .308 Winchester?

Considering that the .243 Winchester was based on the .308 Winchester cartridge, it’s easy to compare and contrast the two. A comparison also reveals the strengths and weaknesses of each. The most notable difference is bullet diameter, which are both reflected in the bullets’ names. This difference is seen in the bullet weight as well; a .243 Winchester has bullets that go up to about 100 grains, while .308 Winchester ammunition will easily go up to 180, giving it far more muzzle energy. Speed, however, goes to the .243, which has cartridges rated over 4,000 feet per second in muzzle velocity; the .308 usually maxes out at about 3,100 feet per second.

Very accurate ammunition grouping well inside of one inch at 100 yards actually grouping inside of 1 and 1/2 in at 300 yards consistently very very precise shooter can't complain at all more than enough energy for any deer at least out to 400 yards from my own experience took it down in 30 ft from point of contact 403 yards! I am very very happy with this I have narrowed my choices between Hornady and Remington they have outperformed everybody else's!

Good for coyotes. But not much of a fan of federal shells. They get the job done.
