It’s difficult to believe, but Remington’s Core-Lokt is a 75-year-old bullet design, and yet, quite unsurprisingly, the no-frills projectiles continue to fill countless freezers each fall. The reason for Core-Lokt’s longevity can pinned to its balance of ballistics and cost. Let’s examine Core-Lokt.

Through the years, I’ve noted that, in spite of the widely touted “mechanical” lock, these cup-and-core projectiles, which are available in both soft-point (SP) and pointed soft-point (PSP) configurations, typically shed considerable weight during expansion and penetration, especially when velocities approach (or are in excess of) 3000 f.p.s.; however, “washed-off” material serves to enhance the projectile’s tissue-disrupting capabilities, which quickens expiration of the animal. For those hunters wanting high retained weight, the newer Core-Lokt Ultra Bonded would be your go-to option, though it’s considerably more expensive. Despite a noteworthy loss of weight and wide upset diameters (oftentimes exceeding two times the bullet’s original diameter), Core-Lokts consistently attain depths necessary for maximum terminal effect-particularly on America’s premier game animal, the thin-skinned and lightly built whitetail deer.

Seldom are recovered Core-Lokts picture-perfect, which some hunters might knock; however, such a quality isn’t necessary for it to perform its function. If you’re holding the upset bullet, then its job was fulfilled. Because of the flat-base projectiles’ less-streamlined shapes, they experience more wind deflection and drop than bullets that are more aerodynamic. This results in less energy delivered on-target. Unless one considers himself or herself a “long-range” hunter, and thus  routinely stretches shots distances beyond 300 yds., then the effects of a lower ballistic coefficient are minimal and a non-issue.    

I’ve found Remington’s Express Core-Lokt center-fire ammunition to exhibit better-than-average accuracy across a wide range of rifles in various calibers; if a particular firearm “likes” traditional-type, heterogeneous bullets, there’s a good chance that Core-Lokts will perform well. I cannot recall an instance in which they performed egregiously accuracy-wise, which is one reason why non-hunters would utilize them, too. The other reasons are: Express Core-Lokt ammunition-in an array of chamberings-is widely available and always among the least-costly options on stores’ shelves. For a general-use “target” load, Core-Lokt’s price is comparable to imported non-full-metal-jacket loads, and the benefit is American-made ammunition with reloadable brass cases of respectable quality. There’s much to like about Core-Lokt. To celebrate Core-Lokt’s 75th anniversary, Remington will offer it in special packaging. What’s your experience with Remington Core-Lokt ammunition?

Why the Murder Rate Quickly Fell to a Likely Historic Low

If the gun-control Left is to be believed, then the murder rate in the U.S. should be going up. After all, gun sales and ownership rates have been rising for the last few decades and anti-gun groups claim that gun ownership is the cause of violent crime. This, of course, is nonsense.
