Best 5.56 Ammo (2026): 8 Loads for Range, Match, Defense and Hunting

Best 5.56 ammo overall

Ammunition Depot: about $11 for 20 · about $500 for a 1,000-round case (49.8¢ a round)

If you want one 5.56 load to stack deep and shoot a lot, this is the one we'd point you to. PMC X-TAC XM193 is the classic 55-grain full metal jacket boat tail, the military M193 recipe, loaded in new, reloadable brass with non-corrosive boxer primers. Ammunition Depot lists it at 3,270 fps and 1,306 ft-lb, the fastest load in this guide on paper.

It also had the best combination of price and owner record we found. On October 5, 2026, a 20-round box was $10.89, a 300-round range bundle $150.99 and a 1,000-round case $498.49 (marked down from $624.99), or 49.8¢ a round, the lowest of any new-production load here. It had 233 reviews averaging 5 out of 5, 92% of them five stars.

Recent owners back that up. A September 2026 reviewer reported no duds or misfires across all his ARs and noted that, because it isn't green tip, it's allowed at more ranges. A May 2026 reviewer ran it for six hours through multiple ARs, suppressed and unsuppressed, and said it worked flawlessly, even in a picky forced-reset-trigger setup.

Best green tip (M855)

Ammunition Depot: about $11 for 20 · about $515 for 1,000 (51.5¢ a round)

"Green tip" is one of the top 5.56 searches right now, and this is the green tip to beat on price and reviews. PMC's X-TAC M855 uses the 62-grain SS109-style bullet, which the listing describes as a lead core with a hardened steel penetrator under the jacket. It's listed at 3,120 fps and 1,323 ft-lb.

On October 5, 2026, a 20-round box was $11.09 (regular $19.99), a 300-round bundle $160.49 and a 1,000-round case $515.49, which is 51.5¢ a round, less than 2 cents more than PMC's own M193. It had 236 reviews averaging 5, with 94% five stars; one August 2026 reviewer said he'd shot thousands of X-TAC rounds without a misfire.

Know why you're buying it. The heavier 62-grain bullet is the standard for rifles with 1:7 or 1:8 twist barrels and it's better at punching through light barriers. But many ranges ban steel-core ammo, especially indoors, and steel-core bullets can damage steel targets. If you only plink on paper, M193 is cheaper and goes more places.

Best name-brand M193

Ammunition Depot: about $16 for 20 · about $81 for 120 · about $640 for 1,000

Winchester's white-box M193 is the other 55-grain FMJ you'll see in every AR owner's closet. Ammunition Depot's listing says it's produced to U.S. military specification, in new, reloadable brass, and lists it at 3,180 fps and 1,235 ft-lb.

It costs more than PMC. On October 5, 2026, a 20-round box was $15.99, a 120-round bundle $80.99 and a 1,000-round case $639.49 (63.9¢ a round). If you want Winchester in bulk, the separate 1,000-round Winchester USA M193 bulk box was $612.39 that day (61.2¢ a round), a little cheaper than the case. We cover that box in our Winchester USA 5.56 M193 bulk review.

Owner reviews are few (9) but all five stars. One July 2026 buyer said he'd shot thousands of rounds of white box without an issue. A 2025 reviewer who normally runs PMC X-TAC liked it but noticed a bigger muzzle flash and a slightly dirtier burn than PMC.

Best American-made green tip

Ammunition Depot: about $14 for 20 · about $565 for 1,000 (56.4¢ a round)

Winchester's M855 is the American-made alternative to PMC's green tip. It's the same idea: a 62-grain FMJ with a small steel cylinder in the core, in new, reloadable brass, listed at 3,060 fps. The listing is blunt about one thing: it says green tip is not acceptable at indoor ranges because it damages them. Check your range's rules before you buy a case.

On October 5, 2026 the 1,000-round case was $564.49, marked down from $824.59, or 56.4¢ a round. That's only about 5 cents a round more than PMC's M855. Smaller packs are much pricier per round: $14.49 for 20 and $195.49 for a 280-round bundle.

It had 28 reviews averaging 5. Most are short and positive ("cycled just fine"); one buyer mentioned a couple of dented rounds, which is worth a quick inspection before you load magazines.

Best 77-grain match load

Ammunition Depot: about $23 for 20 ($1.16 a round)

If your AR has a 1:7 or 1:8 twist barrel and a magnified optic, a heavy match bullet is where you'll see tighter groups and better performance at distance. PMC X-TAC Match uses a 77-grain Sierra open tip match (OTM) bullet, and Ammunition Depot lists it at 2,790 fps and 1,296 ft-lb.

Note that it's loaded as .223 Remington, not 5.56 NATO. That's fine in a 5.56 chamber; it's the reverse (5.56 in a .223-only gun) that makers warn against. On October 5, 2026 a 20-round box was $23.29, marked down from $32.89, and a 200-round case was $232.99, which actually worked out to the same $1.16 a round. At roughly twice the price of bulk FMJ, it's for zeroing, precision work and longer shots, not plinking. There were no owner reviews on this listing yet.

Best home-defense / duty load

Ammunition Depot: about $37 for 20 · about $360 for 200 ($1.79 a round)

FMJ isn't what you want in a home-defense AR. Federal's LE Tactical 55-grain bonded soft point is a law-enforcement load whose listing describes a jacket bonded to the core for consistent expansion and barrier performance, low-flash powder that won't disrupt night vision, and nickel-plated cases with crimped primers. It's listed at 3,150 fps and 1,210 ft-lb. Those are the maker's and retailer's claims; we haven't tested them.

On October 5, 2026 a 20-round box was $37.29 (regular $48.00) and a 200-round case $358.79, or $1.79 a round. Buy enough to fill your magazines and run a couple through your rifle to confirm it feeds and to check your zero; expanding bullets often hit a little differently than FMJ. It's loaded as .223 Remington, which is fine in 5.56 chambers. No owner reviews on the listing yet.

Best deer / hog load for the AR

Ammunition Depot: about $48 for 20 ($2.40 a round)

Where it's legal to hunt deer and hogs with a .223/5.56, you want a tough, bonded bullet, not a varmint or FMJ load. Federal's Fusion MSR is built specifically for modern sporting rifles. The listing says it's tuned for shorter AR barrels with low-flash, fast-burning powder, uses a primer compatible with free-floating firing pins, and has a jacket fused to the core to hold together. It's a 62-grain bonded soft point listed at 2,750 fps and 1,041 ft-lb, with a suggested use of big game.

On October 5, 2026 a 20-round box was $47.99, the most per round in this guide, but you'll only need a box or two a season. It's loaded as .223 Remington. Check your state's minimum caliber rules for deer before you go; some states don't allow .22 centerfire for big game. No owner reviews on the listing yet.

Best varmint load

Ammunition Depot: about $37 for 20 ($1.85 a round)

For coyotes, groundhogs and prairie dogs, a polymer-tipped varmint bullet is the classic choice. Hornady Varmint Express pairs Hornady's 55-grain V-Max with a listed 3,240 fps and 1,282 ft-lb, and the listing describes it as built for rapid expansion on varmints.

On October 5, 2026 it was $36.99 for a 20-round box, sold by the box only. It's loaded as .223 Remington, safe in .223 and 5.56 chambers. The listing photo shows the Varmint Express box without the caliber label visible, so double-check the caliber on the product page when you order. No owner reviews on the listing yet.
