45 ACP – 230 gr FMJ – Remington UMC (L45AP4A – 23781) – 1000 Rounds

The 45 ACP was designed around a 230 grain round nose bullet, and that is still the load most 1911 and 45 pistol owners practice with. This listing is Remington UMC 45 ACP 230 grain full metal jacket ammo in the Mega Pack format, MPN L45AP4A (Remington item 23781), sold as a 1,000 round case for steady range practice and classes.

Remington lists this load at 835 fps with 356 ft-lbs of muzzle energy. The 230 grain FMJ is the original military ball weight for the 45 and produces the slow, heavy push that 45 shooters know well. The round nose profile feeds reliably in pistols with traditional feed ramps, including older 1911s. A full metal jacket does not expand, so this is ammunition for target practice, qualification, and matches rather than self defense.

It fits pistols and carbines chambered in 45 ACP, also called 45 Auto, such as Colt, Springfield, Kimber, and Ruger 1911s, the Glock 21 and 30, SIG P220, HK USP 45, Smith and Wesson M&P45, Springfield XD 45, and Thompson and KRISS Vector carbines. A common question is whether 45 ACP and 45 GAP are interchangeable. They are not. The 45 GAP is shorter and must only be used in guns chambered for it. Another common question is whether this load is subsonic. Yes. At about 835 fps it stays below the speed of sound, which is why 45 ACP is popular with suppressor owners. Many 45 owners also use this load to break in a new pistol before choosing a carry round.

Remington L45AP4A is new production ammunition, not reloads, made in the USA. It uses reloadable brass cases with boxer primers and is non-corrosive. Each Mega Pack box holds 250 rounds, and this listing ships as 4 boxes for 1,000 total, all one lot. The larger boxes cut down on cardboard and keep your practice supply in one place.
