Federal Premium Gold Medal Ammunition 300 Winchester Magnum 190 Grain Sierra MatchKing Hollow Point Boat Tail 20RD

Federal Premium Gold Medal 300 Win Mag ammunition loaded with a 190-grain Sierra MatchKing is purpose-built for competitive riflemen and serious long-range shooters who demand repeatability and precision. This is match-grade ammo for match-grade performance—engineered to deliver the ballistic consistency that wins competitions and tightens groups at distance. Every round in the 20-count box goes through the same meticulous process that made Gold Medal the go-to load for benchrest and F-Class competitors worldwide.

The 190-grain Sierra MatchKing bullet is a boat-tail hollow-point design proven in thousands of match results. Its uniform match jacket and aerodynamic profile give you the ballistic coefficient you need to maintain velocity and energy downrange, even in variable conditions. Federal pairs this legendary bullet with their Benchrest-quality Gold Medal primer—engineered for the sensitivity and ignition consistency that separate tight clusters from flyers. The brass is Federal-produced, and the propellant is specially formulated to deliver velocity and pressures as uniform as your ammunition can be.

If you're loading for a 300 Win Mag bolt gun and accuracy is non-negotiable, Federal Premium Gold Medal with the Sierra MatchKing is the standard against which other long-range ammunition is measured. This is what competitive shooters reach for when they need to print groups, not just send lead downrange.

Frequently Asked Questions

What makes Federal Gold Medal different from standard Federal ammunition?

Gold Medal ammo uses a Benchrest-quality primer and specially formulated propellant designed for the tightest velocity control and primer ignition consistency in Federal's lineup. It's engineered specifically for match and competition use where every variation counts.

Is this ammo suitable for hunting, or is it competition-only?

Federal Gold Medal is designed and proven in competitive shooting. While the 190-grain Sierra MatchKing is an effective long-range bullet, this ammunition is optimized for accuracy and precision rather than hunting-specific performance.

Can I reload this brass?

Yes, Federal brass is known for reloading quality and durability. However, follow standard reloading practices and verify compatibility with your equipment and load data.

What's the ballistic coefficient, and why does it matter?

The Sierra MatchKing has a G1 ballistic coefficient of .533 and a G7 of .275. Higher ballistic coefficient means the bullet resists wind and gravity better downrange, maintaining velocity and energy—critical for long-range accuracy where conditions vary.
