Description
Buffalo Bore's Supercharged line puts serious power in your hands without the premium bullet price tag. This 308 Winchester load pairs a Sierra 180 grain Spitzer-Flat Base bullet with a velocity of 2650 fps and energy rating of 2806 ft-lbs, creating a straightforward, effective round for hunters who want results. The bullet uses standard cup and core construction rather than fancy bonded designs, but that simplicity is part of what makes it work so well at impact velocities of 2750 fps and under.
Reliable Terminal Performance with the Supercharged 308 Win
The name says it all. This is a hot load designed as an all-in-one solution for North American big game. At its designed velocities, the Sierra bullet mushrooms reliably without fragmenting on shoulder bones, which matters when you need penetration on larger game. The mushroom creates a wound channel that puts game down quickly without excessive breakup or ricochet issues. This ammunition ships in factory-fresh brass cases with non-corrosive boxer primers, so you can reload or recycle the cases later if you want.
Straightforward Value for Serious Hunting
Buffalo Bore makes ammunition for people who hunt with .308 rifles, not theoretically or occasionally, but seriously. This load won't drain your wallet before you get to the field. It delivers the velocity and energy needed for effective hunting without forcing you to pay for premium bullet construction you might not need. Each box contains 20 rounds, and cases come packaged 12 boxes per case for serious stockpiling.

Frequently Asked Questions
What's the difference between this load and other .308 options?
Buffalo Bore's Supercharged 308 Win is loaded hot to deliver higher velocity and impact energy than standard factory rounds. The 2650 fps velocity pushes the Sierra bullet faster than mild loads, creating more dramatic expansion and energy transfer on game-sized targets. This makes it particularly effective for hunters who need reliable terminal performance without paying extra for premium bonded bullets.
Will this Spitzer Supercharged round work in my .308 rifle?
This ammunition is designed for all standard .308 Winchester and 7.62 NATO rifles in normal operating condition. The brass cases are boxer primed, making them reloadable or recyclable after firing. Always verify your rifle's chamber and operating condition before firing any unfamiliar ammunition.
How does the Sierra bullet perform on large game?
The Sierra 180 grain Spitzer-Flat Base bullet in this load has proven track record on North American big game. At impact velocities of 2750 fps and under, it mushrooms reliably without breaking apart, even when striking heavy shoulder bones. This mushrooming creates a substantial wound channel for quick, ethical performance on deer and elk-sized game.
Is this loaded hotter than standard factory .308 ammunition?
Yes, the Supercharged designation means this load runs at higher velocity and energy than many standard factory rounds. The 2650 fps velocity is on the stronger side of the .308 spectrum, which is why Buffalo Bore calls it supercharged. Your rifle needs to be in good working order to handle the higher pressures safely.
