Fluted Bullets refer to projectiles that have grooves or channels cut into their surface. These grooves are the "flutes" from which the bullet gets its name.
Fluting is a unique process that not every manufacturer will do, but some very specialized ammo producers will pre-flute their projectiles as a way to ensure the bullet impacts and expands evenly and reliably.
The fluting is a deliberate and measured imperfection milled or filed into the projectile, essentially weakening the projectile in a very specific place to a very specific depth.
This fluting will be done in a uniform pattern around the rim of the hollow point, so that the whole projectile is affected and will expand reliably when the bullet hits its target.

Basic Definition
Fluted bullets are bullets designed with longitudinal grooves or channels on their outer surface. These flutes can vary in number, depth, and configuration depending on the design and intended purpose.
Purposes of Fluting
Reduced Surface Area
Fluting can decrease the bullet's contact area with the barrel's rifling, potentially reducing friction and barrel wear.
Improved Lubrication
The flutes can hold lubrication, ensuring consistent bullet-to-barrel interactions and potentially enhancing accuracy.
Weight Reduction
Removing material can lighten the bullet, which may influence its ballistics, especially its velocity.
Controlled Expansion
In some designs, especially for hunting or self-defense ammunition, flutes can help control the bullet's expansion upon impact.
Availability & Use
Fluted bullets are less common than traditional smooth or jacketed bullet designs but can be found in specific ammunition lines or brands targeting precision shooting, hunting, or specialized applications.
They can be used in both handguns and rifles, depending on the design and intended use.
Performance Factors
The performance of fluted bullets, like any bullet design, can vary based on multiple factors, including the gun's barrel, the cartridge's powder load, and the shooting conditions. Some shooters might find fluted designs to offer advantages in accuracy or consistency, while others might prefer traditional designs.
In summary, fluted bullets in the shooting sports world represent a specialized bullet design that offers potential benefits in terms of friction reduction, lubrication, and controlled expansion.
As with any ammunition choice, their effectiveness and suitability will largely depend on the specific shooting application and personal preferences of the shooter.
