Remington .308 Winchester Ammo Guide: Core-Lokt, Core-Lokt Tipped & AccuTip Compared

1. Remington’s .308 Winchester Lineup — Past and Present

Remington has been loading .308 Winchester ammunition since the cartridge’s commercial introduction in 1952. The Core-Lokt bullet, introduced back in 1939, became the foundation of their hunting ammunition line and has accounted for more deer harvested in North America than any other commercial bullet design. That’s not marketing hyperbole — it’s a function of being the most widely available, most affordable hunting bullet for the better part of a century.

After Remington’s bankruptcy and acquisition by Vista Outdoor (now part of the Remington Firearms family under RemArms), the ammunition division relaunched with a refreshed product lineup. The original Core-Lokt remains, joined by the Core-Lokt Tipped (a polymer-tipped evolution) and the Premier AccuTip for precision hunting applications.

2. Remington .308 Product Comparison Table

Key takeaway: Remington’s .308 lineup is focused on hunting, with three tiers of terminal performance (Core-Lokt, Core-Lokt Tipped, AccuTip) plus budget FMJ for training. The Core-Lokt Tipped offers the biggest upgrade in BC and trajectory over the classic design.

3. Core-Lokt — The Bullet That Built Remington’s Reputation

The Remington Core-Lokt is the most successful commercial hunting bullet in American history. The “controlled expansion” design uses a mechanical lock ring that keeps the lead core attached to the copper jacket during expansion, reducing core-jacket separation compared to standard soft points.

How Core-Lokt Works

The Core-Lokt bullet features a progressively tapered jacket that’s thicker at the base and thinner at the nose. A raised belt inside the jacket physically locks the core in place. On impact, the thin nose section peels back and mushrooms while the locked core maintains enough structural integrity for adequate penetration. It’s not bonded — the mechanical lock is less robust than chemical bonding — but it’s significantly more reliable than an unbonded soft point.

150 Grain PSP Performance

The 150-grain Core-Lokt at 2,820 fps has been the standard American deer hunting load for decades. In gel testing, it typically expands to approximately .54 inches (1.75x caliber) and penetrates 18-19 inches. Recovered bullet weight averages 100-110 grains — roughly 67-73% weight retention. That’s adequate for broadside deer shots and moderate quartering angles, but it can struggle on heavy bone impacts where a bonded bullet would hold together better.

180 Grain PSP Performance

The 180-grain at 2,620 fps is Remington’s larger-game option. The heavier bullet provides more momentum and sectional density for deeper penetration on elk, moose, and black bear. The higher BC (.383 vs .314) also gives better trajectory and wind resistance at extended range.

The Honest Assessment

Core-Lokt works. It has for 85+ years. On clean broadside shots at moderate range, it drops deer reliably. Where it falls short is on tough angles, heavy bone, and extended range — the relatively low BC (.314 for the 150-grain) means more drop and drift than modern polymer-tipped alternatives, and the non-bonded construction limits penetration reliability on difficult shots.

Key takeaway: Core-Lokt is the proven, affordable .308 deer load. It works for straightforward hunting scenarios. For tough angles, larger game, or extended-range shots, upgrade to Core-Lokt Tipped or AccuTip.

4. Core-Lokt Tipped — The Modern Upgrade

Remington’s Core-Lokt Tipped takes the classic Core-Lokt design and adds a polymer tip, redesigned jacket profile, and boat-tail base. The result is a significantly more aerodynamic bullet with better terminal consistency — essentially what Core-Lokt should have evolved into decades ago.

What Changed

The polymer tip serves two functions: it improves the ballistic coefficient by creating a more streamlined nose profile, and it drives into the lead core on impact to initiate more consistent expansion. The boat-tail base (absent on the original Core-Lokt) reduces base drag for better BC and improved accuracy. The jacket profile has been refined for more uniform expansion across a wider velocity range.

BC Improvement

The numbers tell the story. The 150-grain Core-Lokt Tipped has a BC of .415 compared to .314 for the original — a 32% improvement. The 180-grain jumps from .383 to .480 — a 25% increase. That translates to meaningful trajectory and wind drift advantages at hunting distances. At 300 yards, the 150-grain Tipped drops approximately 2 inches less than the original and drifts 1.5 inches less in a 10 mph crosswind.

Terminal Performance

In gel testing at 50 yards with approximately 2,675 fps impact velocity, the 150-grain Core-Lokt Tipped penetrates roughly 18 inches with an expanded diameter of approximately .54 inches. Recovered weight averages around 102 grains — essentially identical to the original Core-Lokt. The terminal performance is similar, but the improved BC means you arrive at the target with more velocity and energy, especially beyond 200 yards.

Accuracy Improvement

Independent testing shows the Core-Lokt Tipped averaging approximately 1.5 MOA across multiple rifles, with some rifles printing sub-MOA groups. The boat-tail design and polymer tip contribute to noticeably tighter groups than the original flat-base Core-Lokt.

Key takeaway: Core-Lokt Tipped is the upgrade the original Core-Lokt needed. Better BC, better accuracy, similar terminal performance, modest price premium. If you’re a Core-Lokt loyalist, this is the evolution worth making.

5. Premier AccuTip — Remington’s Precision Hunting Load

The Premier AccuTip is Remington’s most accurate hunting load. It uses a polymer-tipped boat-tail bullet with tighter manufacturing tolerances than either Core-Lokt variant. Remington requires all AccuTip loads to shoot three five-shot groups under 0.8 inches at 100 yards during quality control — a standard that puts it in the same accuracy tier as Federal Fusion and Hornady Precision Hunter.

165 Grain AccuTip Performance

The 165-grain AccuTip at 2,700 fps delivers a BC of .447 — competitive with Hornady’s SST and Federal’s Fusion in the same weight class. The polymer tip initiates rapid, consistent expansion, and the boat-tail base provides the aerodynamic efficiency needed for reliable 300+ yard performance. Remington rates the 165-grain AccuTip for ethical use out to approximately 450 yards.

Terminal Design

The AccuTip uses a progressively tapered jacket similar to Core-Lokt but with tighter manufacturing specifications. The polymer tip drives into the lead core on impact, creating a consistent mushroom shape. Weight retention typically runs 65-75% — not bonded-bullet territory, but adequate for deer and medium game through moderate angles.

Where AccuTip Excels

The AccuTip’s real advantage is accuracy. The combination of tight OAL tolerances, consistent powder charges, and the polymer tip/boat-tail bullet design delivers match-adjacent accuracy from hunting rifles. If your hunting involves precise shot placement at extended range — western open-terrain hunting, food plots at measured distances, or any scenario where you need to hit a specific spot rather than just center-of-mass — AccuTip delivers.

Key takeaway: AccuTip is Remington’s premium hunting option for shooters who prioritize accuracy. The 0.8-inch accuracy guarantee and superior BC make it the best Remington choice for hunting beyond 200 yards.

6. UMC — Budget Training and Range Ammo

Remington UMC (Union Metallic Cartridge) is their budget training and range ammunition line. The 150-grain FMJ at 2,820 fps is straightforward range ammo — no frills, no terminal performance considerations, just affordable practice rounds.

What You Get

UMC uses standard brass cases, reliable primers, and a basic copper-jacketed FMJ bullet. It’s manufactured to looser tolerances than AccuTip or even Core-Lokt, which means wider velocity spreads and larger groups. Expect 2-3 MOA from a bolt-action rifle — functional for general practice and breaking in new barrels.

Value Comparison

UMC typically prices competitively with Federal American Eagle and Winchester USA White Box. All three are roughly equivalent in quality and purpose. Choose based on availability and price — there’s no meaningful performance difference between budget .308 FMJ loads from major manufacturers.

Key takeaway: UMC is range ammo. Buy whichever budget .308 FMJ is cheapest and available. Save your money for quality hunting ammunition where bullet performance actually matters.

7. Core-Lokt vs Core-Lokt Tipped — Head-to-Head Comparison

Since Core-Lokt Tipped is positioned as the evolution of the original, here’s the direct comparison on every metric that matters.

The verdict: terminal performance (penetration, expansion, weight retention) is nearly identical between the two. The Tipped version wins decisively on BC, trajectory, and accuracy. If you’re shooting under 150 yards in thick timber, the original Core-Lokt saves you money with no practical disadvantage. Beyond 200 yards, the Core-Lokt Tipped’s trajectory and accuracy advantages are worth the premium.

Key takeaway: Core-Lokt Tipped doesn’t kill deer better than the original — it gets the bullet to the deer more precisely and with more retained energy at distance. That distinction matters past 200 yards.

8. Choosing the Right Remington .308 for Your Application

Budget Deer Hunting (Under 200 yards)

Pick: Core-Lokt 150gr PSP. The proven standard. Decades of deer-harvesting track record at the lowest per-round cost in Remington’s hunting lineup.

All-Around Deer Hunting (Under 350 yards)

Pick: Core-Lokt Tipped 150gr. The BC and accuracy upgrades make a meaningful difference past 200 yards. The modest price premium over original Core-Lokt is easily justified.

Elk and Large Game

Pick: Core-Lokt Tipped 180gr. The heavier bullet provides the sectional density and momentum needed for larger animals. The .480 BC gives excellent trajectory out to 300+ yards.

Precision Hunting (300+ yards)

Pick: Premier AccuTip 165gr. The accuracy guarantee and high BC make this the best Remington choice for shots where precise placement matters. Western hunting, food plots, and open terrain applications.

Range Training

Pick: UMC 150gr FMJ. Cheapest Remington .308 option. Buy based on price and availability — all budget FMJ loads perform similarly.

Key takeaway: Remington’s .308 lineup covers budget through precision hunting. The Core-Lokt Tipped is the sweet spot for most hunters — better than the original without AccuTip’s price premium.

9. Remington vs Federal vs Hornady — Brand Comparison

Remington’s strength is their heritage and value at the budget tier — Core-Lokt is still one of the most affordable quality hunting bullets available. Where Remington falls behind is in precision/match ammunition (they don’t currently offer a competitive match .308 load) and in premium hunting technology (AccuTip is good, but it doesn’t match the terminal engineering of Hornady’s ELD-X or Federal’s Terminal Ascent).

Key takeaway: Remington excels at affordable, proven hunting ammunition. For precision shooting or cutting-edge terminal technology, Federal and Hornady have broader offerings. For budget deer hunting, Core-Lokt remains one of the smartest values available.

10. Frequently Asked Questions

Is Remington Core-Lokt still good ammo?

Yes. Core-Lokt has killed more North American deer than any other commercial bullet. The design works for broadside and moderate-angle shots on deer-sized game at typical eastern hunting distances (under 200 yards). It’s not the most technologically advanced option, but it’s proven, affordable, and widely available.

What’s the difference between Core-Lokt and Core-Lokt Tipped?

Core-Lokt Tipped adds a polymer tip, boat-tail base, and redesigned jacket profile. The result is a 32% higher BC (better trajectory and wind resistance), improved accuracy (1.5 MOA vs 2.0 MOA average), and slightly higher velocity. Terminal performance (expansion and penetration) is nearly identical between the two.

Is Remington AccuTip worth the price?

For precision hunting applications, yes. The 0.8-inch accuracy guarantee puts it in the same tier as Federal Fusion and Hornady Precision Hunter. If your hunting involves shots beyond 250 yards where precise bullet placement matters, the AccuTip’s accuracy and BC advantage over Core-Lokt variants justify the premium.

Did Remington ammo quality change after the bankruptcy?

Post-acquisition quality has been generally well-received. The Core-Lokt and Core-Lokt Tipped lines maintain the performance standards expected from the brand. Early post-acquisition batches had some availability issues, but current production is consistent and widely distributed.

Can I use Core-Lokt for elk?

The 180-grain Core-Lokt or Core-Lokt Tipped can be used for elk, but it’s not the ideal choice. The non-bonded construction means the bullet may lose significant weight on heavy bone impacts. For elk, consider a bonded bullet like Federal Fusion or Barnes TTSX for more reliable penetration from all angles.

What Remington .308 load is most accurate?

The Premier AccuTip 165gr is Remington’s most accurate .308 hunting load, with a factory guarantee of sub-0.8-inch groups at 100 yards. Core-Lokt Tipped is the second most accurate, typically printing around 1.5 MOA. Original Core-Lokt averages approximately 2.0 MOA.
