For instance, a 200-grain bullet from the 35 Whelen might have a muzzle velocity round 2700 ft per second (fps), delivering roughly 3200 foot-pounds of power on the muzzle. A 225-grain bullet from the 338-06 would possibly journey at the same pace, however would possibly carry extra power due to its heavier bullet. These figures can range relying on the particular load, bullet sort, and rifle barrel size.
Trajectory: Charting the Flight Path
When looking, realizing a bullet’s trajectory is essential. The flatter the trajectory, the much less holdover compensation a hunter should use at longer ranges. The 338-06, with its increased BCs in lots of instances, tends to have a flatter trajectory than the 35 Whelen, particularly at longer ranges. This makes it barely simpler to precisely place photographs at various distances.
For instance, if each cartridges are sighted in at 200 yards, the 338-06 will sometimes have much less bullet drop at 300 yards, although the distinction is probably not excessive. The 35 Whelen, being heavier on the bullet weight, will drop additional on the identical distance.
Sectional Density: The Penetration Issue
Sectional density, a measure of a bullet’s weight relative to its diameter, is a major think about penetration. Increased sectional density typically signifies higher penetration. Due to the bullet development greater than the diameter distinction, each of those calibers are able to deep penetration. Nevertheless, given the burden and development, the 338-06 and the 35 Whelen carry out equally.
On the Hunt: Actual-World Purposes
The final word check of any cartridge is its efficiency within the discipline. Each the 338-06 and the 35 Whelen have confirmed themselves on quite a lot of sport.
Efficient Vary: Placing Ballistics into Follow
Figuring out the efficient vary for each cartridges requires a cautious consideration of trajectory, power, and the hunter’s ability. Whereas each rounds can be utilized at varied distances, the 338-06, with its flatter trajectory and better BCs, might supply a bonus at longer ranges. Nevertheless, this can be a matter of private choice and the hunter’s consolation with bullet drop.
The 35 Whelen is greatest fitted to photographs inside 300 yards, the place its substantial power and bigger bullet diameter ship most affect. The 338-06 is more likely to carry out at its greatest at round 300 yards or past.
