Remington Core-Lokt Ammunition 300 Remington Ultra Magnum 180 Grain Core-Lokt Pointed Soft Point Box of 20
Remington Core-Lokt Tipped Rifle Ammunition;To be fair, more hunters than any other have trusted Remington Core-Lokt for large game hunting since 1939. More tags have been filled by it on more continents than by any other load. The first bullet designed for controlled expansion is Remington Core-Lokt Tipped Rifle Ammunition. For more than 75 years, hunters have chosen it first due to its dependable performance over time.
With a strong lead core and a tapering copper jacket, the combination provides tremendous 2X expansion, weight retention, and reliable in-game performance. Available in a variety of bullet weights for almost every centerfire hunting calibre manufactured, both soft point and pointed soft point versions are also available. The all-time best-selling hunting ammo is what you should trust for your next hunt. This ammo comes in boxer primed, reloadable brass cases and is fresh production, non-corrosive ammunition.
The Remington-owned Peters Cartridge Co. debuted the “Belted,” a controlled-expansion bullet type, in the late 1930s. Despite being difficult to construct, the design was rather straightforward. The Belted.30 cal.
The bullet was originally a hollow point, 220-grain standard with a jacket made of gilt metal. A narrow, distinct band around the outside increased the weight to 225 grains and was swaged into the bullet’s final diameter.
Upon impact, the nose of the bullet started to upset, but it was checked by the band, and expansion was limited. With expansion curbed, though, the bullet did retain most of its weight to penetrate deeply.
It’s not much of a stretch to say that Remington based its Core-Lokt bullet on the Belted. However, original Core-Lokts were constructed with a thickened jacket on the outside at the midpoint of the jacket. In the final swaging of the bullet, the thick jacket was pressed inward to lock it to the core.
It was plain to see the Core-Lokt was the better of the two bullets in ease of manufacture and performance on game. Remington initially loaded the bullet in Open Point (or “mushroom”) and Soft Point forms for 18 cartridges in its Kleanbore Hi-Speed and Express ammunition.
Peters eventually dropped its Belted bullet in favor of the Core-Lokt. In the Peters brand of cartridges, however, the bullet was called the “Inner-Belted.”
The production of commercial ammunition was halted during World War II, and Remington didn’t reintroduce its Core-Lokt Pointed Soft Point rounds until 1952. Back then, few hunters were concerned about shooting game at long range. Still, PSP bullets had a BC that was roughly 40% greater than Soft Point projectiles. PSP bullets were made with shallow incisions to start the expanding process and a thin jacket at the tip..
In 2010, Remington introduced the Core-Lokt Ultra Bonded featuring a PSP bullet with its lead core bonded to its jacket. Remington advertisements stated the bullet expanded at all practical velocities and yet retained 95 percent of its original weight. The bullets are currently loaded in Remington’s Hypersonic Bonded cartridges. They cost about 50 cents apiece more than Core-Lokt cartridges.
Jon Langenfeld has worked as a product engineer for Remington Ammunition during the past 10 years and was recently promoted to manager of the research and development team.
Langenfeld wears many green Remington hats supervising production of all aspects of rimfire, centerfire and shotshell ammunition and also the components to make the ammunition.

While it may seem simple to add a polymer tip to a Core-Lokt bullet, Langenfeld stated that creating a custom load for a cartridge can take up to six months from start to finish. Remington Core-Lokt Tipped Ammunition for Rifles
It takes time to choose a propellant and a charge weight. In the unlikely event that a vendor is unable to provide the powder we had intended to load, we also evaluate other powders, according to Langenfeld.
Cartridge loads are also evaluated for velocity, pressure, and accuracy under various environmental circumstances because the cartridges may be shot in the sweltering summer heat or the freezing winter months. Remington Core-Lokt Tipped Ammunition for Rifles
Large sample runs on loading machines require time as work moves toward a final load for a particular cartridge. According to Langenfeld, “We test those loads in four or five different rifles with different barrel lengths and action types.” Remington Core-Lokt Tipped Ammunition for Rifles
Functioning issues may arise or accuracy may not be quite up to par. Adjusting bullet seating depth may be all that’s required to solve such problems.
“The proof of all that testing is when the cartridges are scaled up to production levels,” Langenfeld said.
To determine how precisely Remington cartridges topped with Core-Lokt Tipped bullets were loaded, I put some .308 Win. cartridges under the microscope, so to speak, of a Hornady Lock-N-Load Bullet Comparator and RCBS Case Master Gauging Tool. Remington Core-Lokt Tipped Rifle Ammunition
The length of the 165-grain Tipped bullets’ ogive, measured from the face of the case, was measured using the Bullet Comparator. Just 0.003′′ separated the five cartridges’ lengths.
For five cartridges, the Gauging Tool showed bullet runout of 0.002, 0.0015, 0.002, 0.001, and 0.0015. The five cartridges’ total cartridge lengths differed by 0.006′′. A lot of handloaders desire to be able to replicate such precise bullet placement. Remington Core-Lokt Tipped Ammunition for Rifles
Initially, Remington is loading nine cartridges and thirteen loads of its Core-Lokt Tipped bullets, ranging from.243 Win. loaded with 95-grain bullets to.300 Win. Mag. loaded with 180-grain projectiles.
A boattail is worn by all Tipped bullets, with the exception of the.243-cal, which has a flat base. According to Langenfeld, certain Tipped bullets have a secant ogive, but others have a tangent form.
Magazine articles and online discussions demonstrate the growing interest in long-range shooting, and businesses would be losing out if they didn’t provide products to satisfy that need. Therefore, improving the aerodynamics of Core-Lokt bullets is the main goal of the green polymer tip.
For instance, the 150-grain PSP Core-Lokt in.30 calibre has a G1 BC of 0.314, whereas the Tipped bullet with the same weight and diameter has a BC of 0.415. If both bullets are shot at 2,820 fps from a.308 Win at 300 yards, the Tipped bullet’s greater BC causes roughly 1.5 inches of drop and 180 fps more velocity than the PSP Core-Lokt.

Moreover, the PSP only holds onto 51% of the initial energy, compared to 60% for the Tipped bullet. The Tipped bullet significantly outperforms the PSP at 500 yards, with 8.5 inches less drop and 263 feet per second more velocity. Remington Core-Lokt Tipped Ammunition for Rifles
Additionally, the Tipped bullet has retained 41% of its initial energy as opposed to the PSP’s 31%. The Tipped bullet’s benefit can also be seen in the fact that, at 500 yards, it has roughly the same energy and velocity as the PSP bullet, which is comparable at 350 yards.
So increased downrange performance is accomplished with the Tipped bullet’s better ballistics, not by firing a regular bullet from a larger cartridge with more propellant to achieve that higher velocity. A 180-grain Tipped bullet, fired at 2,745 f.p.s. from a .30-’06 Sprg. has only about 3″ of additional drop at 400 yards compared to a .300 Win. Mag. firing a 180-grain PSP bullet with a muzzle velocity of 2,980 f.p.s.
Core-Lokt Tipped bullets are formed with a hollow point, filled with a polymer tip. On contact with game, the tip is shoved back into the hollow point to start expansion. “Once the initial expansion starts, fluid can now flow into the cavity of the bullet, causing full expansion,” Langenfeld said. “Tipped bullets provide very similar performance on game as regular Core-Lokt bullets.”
Controlling that expansion can be a problem. Remington Core-Lokt Tipped Rifle Ammunition do this with a thin jacket at the nose that progressively thickens halfway down its length and then somewhat thins toward the shank.
This hourglass shape tightly swages the jacket to the core and helps hold the core in place in the jacket when the bullet expands. I cut a .30-cal. 165-grain Tipped bullet lengthwise in half to look for that thickened section. Remington Core-Lokt Tipped Rifle Ammunition
The cannelure was the only part of the jacket visibly crimped into the core. Melting out the lead core failed to show any hourglass figure to the jacket, however, the jacket greatly thickened from the nose toward the middle and down to the base. Remington Core-Lokt Tipped Rifle Ammunition
Langenfeld and I went on a Texas mule deer hunt to test the Tipped bullets (sidebar, below), during which he carried a custom .270 Win.-chambered rifle.
The 130-grain Core-Lokt Tipped bullet he fired from it hit his buck through the lungs and broke the far shoulder where it came to rest. The bullet expanded back about three-quarters of its length and retained its core to hold onto 51 percent of its original weight.
I shot a 165-grain Core-Lokt Tipped bullet from a .308 Win.-chambered rifle that hit my buck at a distance of about 150 yards. Remington Core-Lokt Tipped Rifle Ammunition
The bullet shattered the buck’s near humerus bone, plowed through the front of the lungs and broke the opposite humerus, where it stopped. After that rough ride, the recovered bullet had been mashed pretty flat, however, some of the core remained attached to the jacket, and the bullet weighed 61 grains—or 37 percent of its original weight.
I’ve shot Remington factory-loaded Core-Lokts and handloaded Core-Lokt bullets for decades. Just the other day, I found a box of 6 mm 100-grain Pointed Soft Point Core-Lokt bullets. The red box wore a $7.83 price tag, and I must have bought them at least 45 years ago.
For old times’ sake, I handloaded a batch of them with 46.5 grains of W780 propellant in .243 Win. cases. On a blustery November day, I shot them through a pre-’64 Winchester Model 70 Featherweight, and my five, three-shot groups at 100 yards averaged 1.56″.
