300 Wm Vs 300 Wsm
300 Wm
The .300 Winchester Magnum (Wm) is a long-range cartridge designed for big game hunting. It is a versatile cartridge that can be used for hunting elk, deer, and other large game animals. The .300 Wm has a longer case length than the .300 Wsm, which allows it to hold more powder and generate higher velocities.
300 Wsm
The .300 Winchester Short Magnum (Wsm) is a shorter, fatter cartridge that was designed to deliver the same performance as the .300 Wm in a shorter package. The .300 Wsm has a shorter case length, which makes it easier to handle and faster to reload. It also generates less recoil than the .300 Wm.
300 Wm Vs 300 Wsm: What’s the Difference?
The main difference between these two cartridges is their size. The .300 Wm is a bigger cartridge than the .300 Wsm, which means it can shoot heavier bullets at longer ranges. However, this also means it has a bigger recoil and is more expensive. On the other hand, the .300 Wsm is a smaller cartridge with a lighter bullet, but it has lesser recoil and is less expensive.
Ballistics Comparison
The .300 Wm has a flatter trajectory and greater range than the .300 Wsm due to its higher velocities. The .300 Wsm, on the other hand, has a shorter, fatter case that provides better powder combustion and generates less recoil. The .300 Wsm has a shorter effective range than the .300 Wm but is still capable of delivering a lethal blow to big game animals at medium ranges.
Recoil Comparison
The .300 Wm generates more recoil than the .300 Wsm due to its higher velocities and longer case length. The .300 Wsm, on the other hand, generates less recoil and is easier to manage, making it a great choice for hunters who are sensitive to recoil.
Accuracy Comparison
Both the .300 Wm and .300 Wsm are accurate cartridges capable of delivering sub-MOA accuracy. However, the .300 Wm has a flatter trajectory and greater range due to its higher velocities, making it a better choice for long-range shooting.
Hunting Applications
The .300 Wm and .300 Wsm are both excellent cartridges for hunting big game animals like elk, deer, and moose. The .300 Wm is a better choice for long-range hunting due to its higher velocities and flatter trajectory, while the .300 Wsm is a better choice for medium-range hunting due to its lower recoil and faster reloading.
Price Comparison
The .300 Wm is generally more expensive than the .300 Wsm due to its longer case length and higher velocities. However, both cartridges are relatively affordable and offer excellent performance for their price.
Why Choose .300 Wm Vs .300 Wsm?
- If you need longer range and accuracy, go for .300 Wm.
- If you prefer lesser recoil and lower cost, go for .300 Wsm.
