What are Signs Of A Well-Constructed .35 Whelen Cartridge?

Case Capacity and Bullet Seating

A well-constructed .35 Whelen cartridge starts with a consistent case capacity. This is achieved by maintaining a consistent primer pocket depth and a precise case length. The recommended case length is 2.475 inches, which allows for a maximum case capacity of 73.5 grains of water. The optimal bullet seating is achieved by ensuring the bullet is seated at least 0.050 inches off the lands. This allows for a consistent expansion pattern and minimal loss of velocity.

Powder Charge and Velocity

A suitable powder charge for the .35 Whelen cartridge is essential to achieve optimal velocity while maintaining manageable recoil. A charge of 65-70 grains of H4831 or 75-80 grains of IMR 4831 can produce a muzzle velocity of 2,500-2,700 feet per second. This range of velocities ensures that the bullet can penetrate deep into the elk’s body while minimizing the risk of over-penetration. It’s essential to note that the optimal powder charge may vary depending on the specific bullet weight and type used.

Ballistic Performance and Elk Hunting

The .35 Whelen cartridge is well-suited for elk hunting due to its high kinetic energy and flat trajectory. With a bullet weight of 225-250 grains, the cartridge can deliver a kinetic energy of 3,500-4,000 ft-lbs at 200 yards. This level of energy is sufficient to knock down an elk humanely, while the flat trajectory ensures that the bullet can reach the elk’s vital organs from a reasonable distance. When hunting elk, it’s essential to aim for the chest or the area between the front legs to ensure a quick and humane kill.
