Best .308 Ammo for Hunting & Long Range (2026)

If there's one centerfire rifle round that earns the title "do-everything," it's the .308 Winchester. It drops whitetail in the timber, reaches across a canyon for elk, rings steel at 1,000 yards in the hands of a skilled shooter, and is common and affordable enough to actually practice with. For more than seventy years it has been the benchmark big-bore round every other cartridge gets measured against — and in 2026 it remains the smartest single chambering for a hunter or precision shooter who wants one rifle to do it all.

But "versatile" doesn't mean "one load fits every job." The bullet that performs beautifully on a deer at 200 yards is the wrong choice for a long-range steel match, and the cheap brass FMJ that makes range day affordable has no business in the field. This guide cuts straight to the best .308 loads for the three jobs that matter most — hunting, long-range precision, and the range — then explains the .308-vs-7.62 facts, grain weights and barrel twist rates that let you pick correctly every time.

.308 Winchester vs 7.62 NATO: What's the Difference?

Just like .223 and 5.56, the .308 Winchester has a military cousin: the 7.62×51mm NATO. The two share the same external case dimensions and will chamber in each other's rifles — but the relationship is the reverse of the .223/5.56 situation, and it trips people up. With .223/5.56, the military round runs hotter. Here, it's the opposite on paper: commercial .308 Win is loaded to a slightly higher SAAMI pressure (around 62,000 psi) than the 7.62 NATO (roughly 58,000 psi nominal) — yet military 7.62 brass is typically thicker, with less internal capacity, which evens things out in practice.

So what does that mean for you? For the overwhelming majority of modern rifles, nothing scary: most .308 rifles safely shoot both, and most 7.62 NATO rifles safely shoot both. The one real caution is the older milsurp battle rifles.

• Modern bolt gun or AR-10 marked .308 Win → both are fine. Today's commercial rifles are built for the higher .308 pressure and handle 7.62 NATO without issue.
• Rifle marked 7.62 NATO → both are fine. A 7.62 NATO chamber has the room and headspace to digest commercial .308 as well.
• Older milsurp battle rifle (M1A, FAL, HK91, CETME) → prefer 7.62 NATO, or check with a gunsmith. These were built around the thicker 7.62 NATO brass with generous "milspec" chambers and headspace. Running thin commercial .308 brass through a worn or generous milsurp chamber can over-stress the case on firing.

The bottom line: a modern .308 or 7.62 NATO rifle will happily shoot whatever's on the shelf. It's only the vintage gas-operated battle rifles where you want to be deliberate.

Best .308 Ammo for Hunting

This is where the .308 made its name. With a quality expanding bullet it cleanly takes everything from whitetail to elk, and the right load is the one matched to the game and the distance. These three cover the vast majority of North American big-game hunting.

Matching bullet to game is simple: reach for 150gr for deer-sized animals where flat trajectory and value matter, step up to 165gr as a true all-around weight that handles deer through elk, and choose 178gr and heavier when you're after elk or taking longer shots where a high-BC bullet retains energy and bucks wind. Always confirm your state's minimum-caliber and bullet rules before the hunt.

Best .308 Ammo for Long Range

The .308 built its long-range reputation on heavy, high-BC match bullets that stay consistent shot to shot. For ringing steel at distance and wringing every bit of accuracy out of your rifle, these are the loads serious precision shooters reach for.

Best .308 Ammo for the Range

Practice is where skill is built, and you don't need premium hunting or match ammo to do it. For high-volume range work you want clean, reliable, brass-cased FMJ at the lowest cost per round. These are the proven training loads.

There's no way around it: .308 is expensive to shoot compared to pistol calibers, so buying by the case is where the real savings live. Our bulk ammo buying guide walks through how to stock up smart, and it's worth checking case pricing at retailers like Lucky Gunner and Sportsman's Guide, which frequently run the best per-round numbers on bulk brass-cased .308.

.308 Grain Weight Guide

Like every rifle cartridge, the .308 comes in a spread of bullet weights, and each leans toward a different job. The three bands you'll see most:

• 150 grain — the standard. The most common and cheapest weight. Flat-shooting and versatile, it's the default for both range FMJ and deer hunting, and it stabilizes in every common .308 twist. If you want one weight for general use, this is it.
• 165 grain — the all-purpose pick. A touch heavier for better penetration and retained energy, the 165gr is the true do-it-all weight that handles deer through elk with a quality bonded or controlled-expansion bullet. The smart middle ground for serious hunters.
• 175–185 grain — long-range match. Heavy, high-BC match bullets built for accuracy, wind resistance and retained velocity at distance. The choice for precision and long-range shooting — but the heaviest of these want a faster barrel twist to stabilize.

General guidance, 2026. Exact stabilization and accuracy vary by bullet, barrel length and twist; always confirm your rifle shoots a given load well by checking groups on paper.

Barrel Twist Rates for .308

As with any rifle, your barrel's twist rate — how many inches of barrel it takes to complete one full rotation of the rifling — sets which bullet weights it can stabilize. With .308 the good news is that the common weights all live comfortably inside the standard twists; it's only the heaviest match bullets that get picky. The cheat sheet:

• 1:10 — the standard. Stabilizes the common 150–175gr range that covers almost all hunting and most match shooting. It's the default twist on the majority of .308 rifles and the do-it-all choice.
• 1:12 — older or lighter. Found on many older and lighter-profile barrels. Excellent with 150–168gr loads, but it may not reliably stabilize the heaviest 185gr+ match bullets.
• 1:11.25 / 1:11 — increasingly common. Faster twists now showing up on precision rifles. These handle heavy match bullets well and give you headroom for the 178–185gr+ loads that long-range shooters favor.

Shooting .308 in an AR-10 / SR-25

Running .308 in a gas gun adds one more consideration. Semi-autos like the AR-10 and SR-25 are happiest on mid-weight 168–175gr loads designed for gas operation — think Federal Gold Medal 175gr SMK or Hornady's match offerings. These cycle reliably and are tuned for the pressure curve a gas system wants. Avoid the very lightest varmint-style bullets and the hottest specialty loads, both of which can upset a gas gun's timing. Feed it consistent-pressure ammunition and the action stays smooth, reliable and accurate.

Putting It All Together

The .308's strength is range — it does more jobs well than nearly any other cartridge, and choosing right is simple once you know the rules. Verify your chamber first: a modern .308 or 7.62 NATO rifle shoots both, but milsurp battle rifles want quality 7.62 NATO or a gunsmith's blessing. From there it's load by job — Federal Fusion 150gr for deer, Hornady ELD-X 178gr for elk, Federal Gold Medal 175gr SMK for long range, and Federal American Eagle 150gr FMJ for the range. Get those boxes and your rifle is ready for the field, the match, and everything between.

Because .308 isn't cheap to feed, prices swing widely between retailers and sales come around often. Pick your load by job, then compare live .308 prices before you buy so you stock up at the lowest cost.
