.308 Winchester Ammo: The Best Proven Guide

.308 Winchester is the most proven big-game and precision cartridge in America — decades of deer, elk, and hog hunts behind it, plus a long track record in law enforcement and military precision rifles. It’s also one of the few calibers where the commercial and military versions genuinely can be mixed with far less worry than the 5.56/.223 pair. This guide covers grain weight, the .308-vs-7.62-NATO question, and how it stacks up against the caliber that’s been eating into its market share: 6.5 Creedmoor.

.308 Winchester Ammo: Grain Weight Guide

165gr is the most commonly recommended all-around weight for hunters who want one load that covers deer-sized game without being under-built for the occasional larger animal. Precision shooters competing at distance tend to favor 175gr match-grade loads for their higher ballistic coefficient and better wind resistance.

.308 Winchester Ammo: Is It the Same as 7.62 NATO?

.308 Winchester and 7.62x51mm NATO are close, but not identical — and the relationship is more forgiving than the 5.56/.223 pressure question, though still worth understanding. Commercial .308 Winchester ammunition is sometimes loaded to slightly higher pressure than military-spec 7.62 NATO, and 7.62 NATO brass tends to have thicker case walls, which can reduce case capacity. Most modern rifles chambered in either handle both rounds without issue, but if you own an older military-surplus rifle, or a rifle explicitly marked for one or the other, confirm your manufacturer’s guidance before mixing them — the margin for error here is real, just smaller than with 5.56 vs .223.

.308 Winchester Ammo: Hunting vs Precision Loads

• Hunting loads typically use soft-point or bonded bullets designed to expand reliably on impact — the standard choice for deer, hog, and elk.
• Precision/match loads use boat-tail hollow-point (BTHP) match bullets, optimized for consistency and long-range accuracy rather than expansion — the standard choice for target shooting and law-enforcement precision use, not hunting.

Don’t use match-grade BTHP ammunition for hunting — it isn’t designed to expand the way a hunting bullet is, and won’t perform the same on game.

.308 Winchester Ammo: .308 vs 6.5 Creedmoor

If you’re deciding between the two, we’ve written the full breakdown in our 6.5 PRC vs 6.5 Creedmoor guide, but the short version: 6.5 Creedmoor generally offers flatter trajectory and less recoil at extended range, while .308 Winchester offers more energy on impact, a wider selection of hunting-specific loads, and generally cheaper ammunition. For deer-sized game inside 400 yards, the two are close enough that either is a sound choice — .308’s edge is in bigger game and ammo availability.

.308 Winchester Ammo: Which Should You Buy?

Choose 147–150gr FMJ/soft-point if you:

• Want an affordable, general-purpose range and light-hunting load
• Are training fundamentals in a .308 bolt gun or precision rifle

Choose 165–168gr soft-point if you:

• Hunt deer or hogs and want the most commonly recommended all-around weight
• Want one load that also has margin for larger game

Choose 175–180gr match or premium hunting loads if you:

• Are hunting elk or other large game
• Are shooting precision/long-range and want the highest-BC option in the caliber

Common Buying Mistakes

• Hunting with match-grade BTHP ammunition instead of a proper expanding hunting bullet.
• Assuming military 7.62 NATO surplus is a drop-in match for every .308-chambered rifle without checking the manufacturer’s guidance.
• Buying single boxes instead of bulk case quantities for high-volume range or precision practice, which meaningfully raises cost per round.
• Not re-zeroing after switching load types. Hunting and match-grade ammunition can shift point of impact even at the same grain weight, since bullet shape and seating depth differ — always confirm zero before relying on a new load in the field.

What Experienced Shooters Commonly Recommend

• Most recommended all-around hunting weight: 165gr, cited most often as the balance of trajectory, energy, and versatility across deer-sized game.
• Most recommended for elk: 175–180gr premium bonded or controlled-expansion bullets for reliable penetration on larger animals.
• Most common problem reported: inconsistent accuracy traced to mixing hunting and match ammunition in the same rifle without re-zeroing, not the caliber itself.
• Most common buying mistake: using surplus 7.62 NATO ball ammunition for hunting instead of a proper expanding bullet.

.308 Winchester Ammo: Storage & Maintenance

Store .308 Winchester ammunition cool, dry, and out of direct sunlight — the same rules that apply to any centerfire rifle cartridge. Properly stored factory ammunition, sealed in its original packaging or a container with a desiccant pack, can remain reliable for decades; humidity and temperature swings are the real threat to shelf life, not age alone. After a hunting trip or a heavy range session, clean the bore and bolt face to clear copper and carbon fouling, and re-check your zero before the next trip out — a rifle that’s been through rough field conditions can shift slightly even without any hardware issue.

Please buy and use ammunition responsibly and in accordance with all federal, state and local laws. Confirm your rifle’s manufacturer guidance before mixing .308 Winchester and 7.62 NATO ammunition, and use only proper expanding hunting bullets for game — not match-grade target ammunition. Take only ethical shots within your effective range. You must meet all legal requirements to purchase, and ammunition cannot be shipped to every jurisdiction.

Frequently Asked Questions

Is .308 Winchester the same as 7.62 NATO? They’re close but not identical — .308 Winchester commercial ammo can run at slightly higher pressure, and 7.62 NATO brass is often thicker-walled. Most modern rifles handle both, but check your manufacturer’s guidance, especially with older or military-surplus rifles.

What grain weight is best for .308 deer hunting? 165–168gr soft-point is the most commonly recommended all-around weight for deer-sized game.

Is .308 Winchester better than 6.5 Creedmoor? Neither is universally better — .308 offers more energy on impact and cheaper, more available ammo; 6.5 Creedmoor offers flatter trajectory and less recoil at longer range. See our full 6.5 PRC vs 6.5 Creedmoor comparison for the detailed breakdown.

Can I use match-grade .308 ammo for hunting? It’s not recommended — match-grade BTHP bullets are built for consistency, not expansion, and won’t perform reliably on game the way a proper hunting bullet does.

What’s the best .308 ammo for elk hunting? 175–180gr premium bonded or controlled-expansion loads are the standard recommendation for reliable penetration on larger game.

Is .308 Winchester good for long-range shooting? Yes, particularly with 175gr+ match loads, though 6.5mm-class cartridges have become popular alternatives for shooters prioritizing flat trajectory and low recoil at extreme range.

How much does .308 Winchester ammo typically cost per round? It’s generally more affordable than 6.5 Creedmoor and premium magnum cartridges, especially in bulk 147–150gr FMJ or soft-point loads.

Can I shoot 7.62 NATO surplus ammo in a .308 Winchester rifle? In most modern rifles, yes — but confirm your specific rifle’s manufacturer guidance first, especially with older or military-surplus actions, and never use ball ammunition for hunting.

How long does .308 Winchester ammo last in storage? Properly stored (cool, dry, sealed) factory ammunition can remain reliable for decades. Moisture and temperature swings threaten shelf life far more than age alone.
