Product Details

These cartridges are equipped with an ultra heavy-weight 550-grain full metal jacketed bullet, which is the heaviest 458 SOCOM bullet that SBR produces.

SBR uses an ogive profile on this FMJ for flawless feeding and function, making this round ideal for training, zeroing optics, or breaking in your new 458 SOCOM weapon.

The heavier than standard grain weight and subsonic speeds make this cartridge well-suited for use with suppressors.

• Heavy grain weight
• Subsonic velocity
• Full Metal Jacket
• New brass casings

SBR has been the leader in factory .458 SOCOM production since its creation in 2001 and has continued to research and innovate in the ballistics testing and manufacturing of this high powered cartridge.

The cartridge itself is a powerhouse and was developed specifically to take down large, dangerous game, while still being usable from the M4/AR15 platform (a unique upper receiver would be needed).
