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.

    Berry Berry Good Bullet

    I'm working on loads for my service pistol. These bullets weigh within +/-1 grain of nominal.

    Excellent bullet at a superb price point!

    This is an excellent bullet at a superb price point! I use them in my Kimber Gold Match2 (stainless) with great results seated over a variety of powders! Also use them in my 50 cal T/C Impact muzzleloader with various 50/45 sabots, loaded over Blackhorn 209 propellant and yielding 1800+ f-sec velocity with 11/4" groups @50 yds!

    Bullet Type Full Metal Jacket (FMJ)

    You cannot fire these component projectiles straight out of the box. These are bullets only, and accordingly require the work of a handloader before they can do anything more useful than serve as a 34.4 pound doorstop.

    Do you need simple and economical full metal jacket projectiles before you can start loading your own 45 ACP ammunition? Are you sick and tired of waiting for the stars to align so you can purchase exceedingly rare 45 GAP ammo? Worry not. Winchester has your six.

    These FMJs are a consistent 0.451” in diameter and weigh in at a steady 230 grains. They’re optimal for making your own range and target ammo, since their solid point round nose profiles prohibit any degree of terminal expansion. Winchester’s FMJs are 100% steel-free – they have lead cores and copper-alloy jackets that cannot attract a magnet. The bullets come 100 to a box, 10 boxes to a case. Order today and prepare to start seating!

    Very disappointed

    I bought these bullets a while ago to shoot bullseye at 50 yards. I have loaded these bullets with various different powders and loads and I have come to the conclusion that they just don't shoot accurately. Sorry, but I would not buy them again. I have had other issues with the Hornaday brand and I am staying away.

    Review by Till (Posted on 12/13/2022)

    Very good performing bulk target bullets

    I have purchased a couple cases each of these HAP bullets in 9mm, 45 and 40 caliber. They perform well accuracy wise, I’m getting ¾-1” groups at 25yds out of a Sig P220 and a Wiley Clapp 1911 Government, both with Barsto barrels. I would caution that the jackets are thin or soft as I reloaded some Federal primed brass that had bullet sealant and it caused the cone to deform on the 40 caliber bullets.
