Best 327 Magnum Ammo

What is 327 Magnum ammo?🧐

It is also known as .327 Federal Magnum, which is a type of ammunition for firearms. It’s a relatively modern cartridge introduced in 2008 by Federal Cartridge Company in collaboration with Ruger, a firearms manufacturer. It is designed to offer increased performance compared to smaller handgun cartridges while still maintaining manageable recoil.

327 Magnum ammo


The .327 Magnum ammunition (also known as .327 Federal Magnum) has several notable features that make it unique among handgun cartridges:

✳️ Cartridge Dimensions: It is based on a .32-caliber bullet (.312 inches in diameter) and uses a slightly longer case than its predecessor, the .32 H&R Magnum. The overall length of the cartridge is longer than traditional .38 Special and .357 Magnum rounds.

✳️ Higher Velocity: The longer case allows for increased powder capacity, resulting in higher velocities for the bullets. This translates to improved terminal ballistics and penetration, making it more effective for self-defense.

✳️ Terminal Performance: This cartridge is designed to offer improved stopping power compared to smaller handgun cartridges like the .38 Special. It’s higher velocity and energy contribute to better terminal ballistics, meaning it can create larger wound channels and potentially incapacitate threats more effectively.

✳️ Recoil Management: While it offers increased performance over smaller cartridges, it generally produces less recoil compared to more powerful cartridges like the .357 Magnum. This can make it more manageable for shooters who prefer a balance between stopping power and controllable recoil.

Benefits of 327 Magnum ammunition

Stopping Power💥

The stopping power of any handgun cartridge, including the .327 Magnum, is a topic of debate and depends on various factors. Its performance characteristics, including bullet weight, velocity, and energy, contribute to its stopping power potential. Here are some factors to consider:

💣 Bullet Design: The type of bullet used can significantly influence stopping power. Hollow point or expanding bullets are designed to deform upon impact, creating larger wound channels and transferring more energy to the target. This can enhance the cartridge’s effectiveness in stopping a threat.
💣 Velocity and Energy: The .327 Magnum’s higher velocity and energy compared to smaller cartridges like the .38 Special contribute to better penetration and tissue damage. Increased energy can disrupt vital structures and potentially incapacitate an attacker more quickly.
💣 Shot Placement: Regardless of the cartridge used, shot placement is crucial for stopping power. Accurate shots to vital areas, such as the chest or head, have a greater chance of incapacitating a threat. Its manageable recoil and potentially greater accuracy can aid in accurate shot placement.
💣 Recoil Management: The relatively mild recoil can allow for quicker follow-up shots, increasing the likelihood of hitting the target multiple times and increasing stopping power.
💣 Personal Factors: The effectiveness of a cartridge also depends on the individual shooter’s skill, training, and ability to stay calm under stress. An accurate shooter who can rapidly fire follow-up shots will generally have better stopping power regardless of the cartridge used.

📌 It’s important to note that no handgun cartridge guarantees an instant stop, and stopping power is influenced by a complex interplay of factors.

I’ve been considering carrying a revolver chambered in .327 Federal Magnum, but I’ve come across some concerns that have made me think twice. One issue I’ve heard about is that the .327 Magnum is nearly as loud as the .357 Magnum. Since I value my hearing, this raises concerns, especially if I ever have to use it indoors. I’m curious to know your thoughts on this matter.

    From what I’ve gathered, it seems that the .327 Magnum offers power that’s on par with the lower end of the .357 Magnum spectrum. This suggests that it should be more than sufficient for self-defense purposes. However, I’ve also learned that the .327 Magnum is less common and more expensive compared to the .38 Special, which counts as a downside. But then again, there’s an interesting perk: it opens the door to shooting .32 Long and .32 H&R Magnum rounds, which could be a plus for some individuals.

      I’m quite familiar with the world of the .327 Magnum as I’ve been carrying and shooting this caliber regularly. I must admit, it does come with its fair share of drawbacks, just as you’ve mentioned – expensive ammunition, a limited selection of firearms chambered for it, and yes, it’s not the quietest option out there. However, I’ve developed a particular fondness for it, especially considering I’m into reloading. When the caliber was initially introduced, I took the plunge and got myself a case of factory ammo. Since then, I’ve been maintaining my supply by adding in factory rounds sporadically to replenish any brass that’s been lost or damaged. Sure, the factory stuff can be pricey, but I find that the investment evens out since I can reuse the brass multiple times. In the end, it’s a matter of priorities. I’m fairly confident that any potential threat you’re engaging won’t be concerned about whether you’re using a .38, .357 Magnum, or .327 Magnum. The universal truth that proper shot placement trumps caliber debates holds. So, focusing on regular and affordable training is crucial. For someone like me who reloads and can be more self-reliant with ammo, the .327 Magnum aligns well.

        I’ve been wondering whether the .327 Magnum is a solid choice for self-defense. Is this caliber effective for defense, and if it is, which revolver would be the top pick?

          I’ve come across some impressive feedback regarding the ballistics of the .327 Magnum when fired from snub nose revolvers. However, like many other unique calibers, the cost factor (around 50 cents per round) can be a major deterrent, particularly when it comes to effective training. Unless you have a substantial disposable income, the prospect of loading up a five-shot revolver and sending $2.50 worth of ammo downrange can feel quite discouraging.

            I’ve been eyeing the 327 LCR as a potential option. The ballistics it offers seem to align well with the performance of lighter-weight bullets in snub-nose 357 revolvers or short-barreled 9mm semi-autos, which are often in competition within a similar-sized package. Now, when it comes to reports about its recoil, they’re all over the map, but it appears that the kick is somewhat comparable to that of a 357 Magnum. In terms of benefits, it boils down to two main points: the extra round it offers and the availability of incredibly light-recoiling factory loads that can be used for range practice (thanks to its compatibility with other chamberings). For reloaders like me, I reckon the 327 LCR might not be a bad choice. Reloading opens up the possibility of fine-tuning the recoil impulse over a wide range, all while maintaining a reasonable cost per round.

              I’ve had my eye on the .327 Magnum for a while now, but the price of the revolvers chambered for this round has always held me back. I’m wondering if there’s any hope of .327 ammo becoming affordable and readily available shortly.

                I’ve been mulling over this question myself. Is the .327 Federal Magnum worth considering? From my perspective, the answer is yes, but with a caveat – it’s particularly worth it if you’re into reloading, especially in the current ammo landscape. If you don’t reload, don’t worry – getting started with reloading doesn’t have to break the bank, and if you need guidance, I’d be more than willing to assist. I own a .327 Henry Big Boy rifle in brass. Shooting it is almost like firing a .22 – it’s that gentle. Even the hot loads for the 32 H&R feel like you’re using a BB gun. And that’s from a rifle. When it comes to a lightweight revolver, the .327 Magnum truly shines. It’s notably more manageable than its bigger sibling, the .357 Magnum, especially in terms of recoil. If you’re on the hunt for a carry gun with a light feel, my vote would go to a .327 Magnum revolver without hesitation.

                  Has anyone had the chance to get their hands on, fire, or own one of those .327 Magnum revolvers? I’m genuinely curious if it’s worth taking a closer look at this caliber. I’d love to hear from those who’ve had experience with it. How do these revolvers perform in the real world? Your insights would be greatly appreciated.

                    Now, if we’re talking about a carry gun for self-defense and the need to handle larger critters like coyotes up close, the 327 Federal is just the right cartridge. When it comes to animals like raccoons and porcupines, opting for heavier cast bullets, say above 130 grains, can address any concerns about over-penetration – a challenge that’s easily tackled by switching to jacketed bullets. Although I haven’t had the chance to work with the SP101, I do own an S&W Carry Comp chambered in 327. Sporting a 3″ ported barrel, it’s a bit loud, but I’ve found it to offer a fantastic blend of power and manageability. Here’s an older thread that discusses loading for this cartridge. Trust me, shooting the BHP – Federal Premium HammerDown – 327 Federal Magnum – 127 Grain – 20 Rounds at the range and out in the field is an absolute blast.
