45 GAP Bullets

45 GAP Bullets for Reloading

The 45 GAP is Glock’s first attempt to introduce a new cartridge to the commercial market. You don’t need to guess which cartridge the 45 GAP was meant to improve upon, and indeed the 45 GAP matches the 45 ACP’s power while reducing the chance of a case neck blowout.

The original max bullet weight for the 45 GAP was 200 grains, which is loaded to a higher pressure than 45 ACP to give it equivalent performance. The 45 GAP’s max pressure is 23,000 psi, about nine percent more than the 45 ACP, to make this possible. Since the 45 GAP is a smaller round, its greater pressure is achieved solely via more powerful powders. The 45 GAP has since been determined capable of firing 230 grain bullets, and load data for 150, 160, and 185 bullets are available as well. The 45 GAP’s bullet is .451 in diameter, so finding the correct bullets for reloading is as simple as finding 45 ACP component bullets.

The 45 GAP is a little shorter than its predecessor, with a .755 inch long case instead of .898 inches. Glock intended this to permit the design of smaller handguns. You could theoretically trim down 45 ACP brass to make 45 GAP brass, but their lengths alone aren’t the only thing that make the two cases different. You’re better off loading once-fired 45 GAP brass or investing in brand new cases.

    If you need affordable bullets for punching paper, Berry's bullets are for you. Each projectile in this box of 500 is a Semi Wad Cutter (SWC), has a .452" diameter, and weights 200 Grains. Berry's bullets are made with swaged lead cores that are plated to their final weight, then each projectile is re-struck to ensure the final product is very consistent. Copper plated projectiles are more affordable than jacketed bullets and will not foul your barrel like traditional cast lead.

    Note: Plated Bullets are not recommended for velocities over 1,200 feet per second.

    This is not loaded ammunition. You cannot fire these bullets right after you open their packaging, as they lack cases, powder and propellant. Do not order these component bullets if you do not handload your own ammunition.

    Do order these component bullets if you do handload your own ammunition, though! These 0.452” diameter, 0.610" overall length, 230 grain jacketed hollow points are perfect if you want to make your own 45 ACP self-defense ammo. They’re also perfect if you’re a fan of the 45 GAP and are tired of looking for high-quality ammo for personal protection.

    This is Berry’s Hybrid Hollow Point. It starts out as a swaged lead core, which is electroplated with copper to create zero exposed lead and excellent jacket concentricity. The electroplating process also yields a bonded jacket, so you can count on reliably deep penetration during a self-defense scenario. Every Berry’s bullet is restruck to ensure that it adheres to tight specifications.

    Berry’s advises that these bullets have an effective velocity of 825 to 975 fps. They also advise loading a 1.210” long 45 ACP cartridge. Use a round nose seating stem to avoid damaging the Hybrid Hollow Point’s performance, and do not overcrimp the brass after seating (you can use a roll or taper crimp). Load data are available in any manual or on any propellant manufacturer’s website.

    Great product and fast shipping.

    Great product and fast shipping. They had to ship the order twice because UPS busted the box and lost over half of the bullets. This happen both times. Like I said this is not the fault of Wideners. Would recommend.

    The .45 ACP, which stands for Automatic Colt Pistol, is an incredibly powerful and accurate handgun round that has been used by both law enforcement officials and personal gun owners for years. For anyone concerned with home defense, the .45 ACP is often at the top of their lists. Originally developed to give law enforcement and military more firepower, this round can deliver fast shots, accurate placement, and effective power.

    Reloading .45 ACP cases takes the right type of projectiles, so make sure you order this box of 230-grain reloading bullets. You’ll get 100 bullets that have a jacketed hollow point, giving them consistent mushrooming on impact. The 230-grain bullet, which is one of the larger projectiles for a .45 ACP case, ensures quality penetration.

    Speer is a company that makes excellent rounds under the Gold Dot and Lawman brands. They have a wide variety of handgun cartridges and have become a top choice among law enforcement agencies. From training to case reloading, Speer has the right ammo for the job.
