248s

248s refers to a specific type of rifle cartridge, notably the .248 inches caliber. This caliber is less common than many other rifle cartridges and is often associated with older or more specialized firearms. The .248 inch diameter bullet is approximately 6.25 millimeters. Rifles chambered for this round are typically designed for hunting or target shooting.

Historically, cartridges of this size have been developed for various purposes, often focusing on a balance between projectile velocity and projectile weight for specific applications. While the exact origins of the .248 caliber might be tied to specific firearm manufacturers or periods, its presence in the market has generally been niche. Ammunition for .248 caliber rifles is not as widely available as for more popular calibers, often requiring specialized orders or reloading by the shooter.

The performance characteristics of a .248 round depend heavily on the specific bullet weight, powder charge, and the firearm's barrel length. Generally, smaller caliber bullets like those in the .248 range are known for their high velocity and flat trajectory, which can be advantageous for long-range shooting. However, they may also exhibit less energy transfer compared to larger caliber rounds, making them more suited for smaller game or varmint hunting. The specific rifling twist rate in the barrel is also crucial for stabilizing the projectile.
