What Is .358 Winchester?
The .358 Winchester was introduced by Winchester in 1955 to provide the power of heavier .35-caliber bullets in a short-action rifle. It was created by taking the .308 Winchester case and necking it up to hold a 0.358-inch diameter bullet. The .358 Winchester typically uses heavy bullet weights between 200 and 250 grains.
Generating roughly 2,500 fps with a 200-grain bullet, it produces nearly 2,800 foot-pounds of muzzle energy. Operating at a SAAMI maximum pressure of 52,000 CUP, it delivers heavy recoil and massive energy transfer within 250 yards. Common applications include hunting large, tough game like moose, elk, and brown bear in dense timber where short-barreled lever-action or bolt-action rifles are preferred.
What Is .308 Winchester?
The .308 Winchester was introduced in 1952 as a commercial hunting cartridge, shortly before its adoption by the military as the 7.62x51mm NATO. It uses a 2.015-inch case and fires a 0.308-inch diameter bullet. The cartridge most commonly fires bullet weights ranging from 150 to 180 grains, achieving muzzle velocities between 2,600 and 2,820 fps.
With a SAAMI maximum pressure of 62,000 psi, a typical 150-grain load generates over 2,600 foot-pounds of muzzle energy with moderate recoil. It is famous for its inherent accuracy, barrel life, and efficiency. The .308 Winchester is one of the most widely used cartridges in the world for deer hunting, target shooting, and law enforcement sniper rifles.

The .308 Winchester utilizes higher velocities and higher ballistic coefficient bullets to maintain energy and a flat trajectory over long distances. The .358 Winchester relies on heavy bullet mass traveling at moderate velocities. While their initial muzzle energy figures are similar, the .358 Winchester sheds velocity and energy much faster due to the poor aerodynamic shape of large-diameter, flat-base bullets.
358 Winchester vs 308 Size and Dimensions
Because the .358 Winchester is built directly from the .308 Winchester case, their base dimensions are identical, with the only physical difference being the neck diameter.
Bullet diameter: .358 is 0.358 inches; .308 is 0.308 inches.
Case length: Both are 2.015 inches.
Overall cartridge length: .358 is up to 2.780 inches; .308 is up to 2.810 inches.
Case diameter: Both are 0.470 inches at the shoulder.
Base diameter: Both are 0.470 inches.
Rim diameter: Both are 0.473 inches.
Typical cartridge weight: .358 is approximately 415 grains; .308 is approximately 390 grains.
Both cartridges fit perfectly into short-action rifles. The .358 Winchester simply opens the neck to accommodate the wider projectile, leaving slightly less internal case capacity due to the bullet seating depth required to maintain the short overall cartridge length.
358 Winchester vs 308 Bullet Weight
| Cartridge | Common Bullet Weights | Lightest Common Weight | Heaviest Common Weight | Typical Applications |
| .358 Winchester | 200 gr, 225 gr, 250 gr | 180 gr | 250 gr | Large game, brush hunting, bear protection |
| .308 Winchester | 150 gr, 165 gr, 175 gr | 110 gr | 180 gr | Deer hunting, precision target shooting |
The .358 Winchester uses substantially heavier bullets than the .308 Winchester. The wider 0.358-inch bore diameter requires heavier projectiles to maintain proper sectional density. This weight gives the .358 Winchester incredible bone-crushing penetration at close ranges, making it a favorite for stopping heavy or dangerous game in thick cover.
358 Winchester vs 308 Velocity
The .308 Winchester holds a distinct velocity advantage. Standard 150-grain .308 Winchester loads leave the barrel at over 2,800 fps. Because the .358 Winchester fires bullets weighing 50 to 100 grains more using the exact same powder capacity, its velocities are much lower, typically ranging from 2,250 to 2,500 fps depending on barrel length and ammunition load.
358 Winchester vs 308 Muzzle Energy
When comparing 358 winchester vs 308 muzzle energy, both cartridges are remarkably similar at the muzzle, generally producing between 2,600 and 2,800 foot-pounds.
However, they deliver that energy differently. The .308 Winchester achieves its energy through velocity, while the .358 Winchester achieves its energy through bullet mass. Past 150 yards, the .308 Winchester retains significantly more energy because its aerodynamic bullets resist drag better than the blunt projectiles typically loaded in the .358 Winchester.
358 Winchester vs 308 Recoil
Recoil is influenced by bullet weight, muzzle velocity, powder charge, and firearm weight.
Because both cartridges use similar powder charges in similar short-action rifles, the recoil difference comes entirely from bullet weight. The .358 Winchester pushes a heavier projectile, resulting in noticeably stiffer recoil. A standard .308 Winchester generates about 15 to 17 foot-pounds of recoil energy. The .358 Winchester pushing a 200-grain or 225-grain bullet will generate 20 to 22 foot-pounds of recoil energy, which is comparable to a .30-06 Springfield.
358 Winchester vs 308 Effective Range
Effective range depends heavily on the trajectory of the bullet and the retained energy necessary to perform the desired task.
The .308 Winchester has an effective hunting range of roughly 400 to 500 yards for medium game, and target shooters successfully use it out to 800 or 1,000 yards.
The .358 Winchester is essentially a 250-yard cartridge. Beyond 250 yards, its heavy bullets drop rapidly, making precise holdovers difficult. Within that 250-yard envelope, however, it is a devastatingly effective cartridge.
358 Winchester vs 308 for Hunting
For general hunting, the .308 Winchester is the more versatile choice. It can hunt varmints with light bullets, deer with 150-grain bullets, and elk with premium 180-grain bullets. It works well in open plains, mountains, and forests.
The .358 Winchester is a specialized hunting tool. It shines in dense timber, heavy brush, and swamp environments where shots rarely exceed 150 yards. Hunters pursue black bear, brown bear, moose, and elk with the .358 Winchester because the heavy bullet penetrates deeply and creates a massive wound channel, dropping large game quickly before they can run into thick cover.
358 Winchester vs 308 for Deer Hunting
Both cartridges will cleanly harvest deer, but the .308 Winchester is far more practical for the average deer hunter. The .308 offers a flatter trajectory, lighter recoil, and endless ammunition choices tailored specifically for whitetail and mule deer.
The .358 Winchester is considered overkill for standard deer hunting unless the hunter is pursuing deer in incredibly thick brush where short tracking jobs are a necessity. A 200-grain .35-caliber bullet will anchor a deer instantly, but it damages more meat than a standard .308 Winchester load if shot placement is poor.
358 Winchester vs 308 for Long Range
There is no contest between 358 winchester vs 308 for long-range applications. The .308 Winchester is a legendary long-range cartridge with decades of military sniper and competitive target shooting history. It benefits from exceptionally high ballistic coefficient bullets that resist wind drift and retain supersonic velocity at extended distances.
The .358 Winchester has terrible long-range ballistics. Its bullets are heavy, wide, and usually flat-nosed or round-nosed to fit in lever-action magazine tubes or short-action magazines. These bullets bleed velocity rapidly and drop steeply past 200 yards, making the .358 Winchester completely unsuitable for long-range target shooting.
358 Winchester vs 308 Rifle Size and Weight
Both cartridges are designed for short-action rifles, meaning the receivers are compact and light.
The .308 Winchester is chambered in almost every rifle type imaginable: ultralight mountain rifles, heavy tactical bolt actions, AR-10 semi-automatics, and lever actions.
The .358 Winchester is most famously chambered in fast-handling lever-action rifles like the Savage Model 99 and the Browning BLR, as well as compact bolt-action brush guns. These rifles are typically built to be short, lightweight, and fast to the shoulder, weighing between 6.5 and 7.5 pounds to optimize their use in thick woods.
358 Winchester vs 308 Cost Per Round
The difference in cost and availability is massive. The .308 Winchester benefits from global mass production, while the .358 Winchester is a boutique cartridge often requiring hunters to reload their own ammunition.
| Cartridge | Bullet Weight | Ammo Type | Quantity | Price | Cost Per Round |
| .308 Winchester | 150 gr | FMJ Practice (Brass) | 100 rounds | $75.00 | $0.75 |
| .308 Winchester | 150 gr | Soft Point Hunting | 20 rounds | $25.00 | $1.25 |
| .358 Winchester | 200 gr | Hornady Custom SP | 20 rounds | $55.00 | $2.75 |
| .358 Winchester | 225 gr | Premium Bear Load | 20 rounds | $70.00 | $3.50 |
Shooting the .308 Winchester is highly affordable. Shooting the .358 Winchester with factory ammunition is expensive and requires buying specialized boxes from online retailers rather than local stores.
358 Winchester vs 308 Availability
The .308 Winchester is one of the most widely available centerfire rifle cartridges on the planet. Rifles, ammunition, and reloading components are in stock at virtually every sporting goods store.
The .358 Winchester is essentially a handloader’s cartridge today. Only a few manufacturers, such as Hornady and Winchester, do seasonal production runs of factory ammunition. Rifles chambered in .358 Winchester are rarely found new on standard retail racks and must usually be ordered specifically or purchased on the used market.
