Barnes Precision Match 300 Win Mag 220 Grain OTM Ammunition - 20 Rounds

Barnes Precision Match 300 Win Mag ammunition combines match-grade precision with real-world long-range performance. If you're running a .300 Winchester Magnum for precision rifle competition, extreme-distance hunting, or serious range work, these 220-grain Open Tip Match rounds are built for the shooter who won't settle for anything less than repeatable accuracy. Each box delivers 20 rounds engineered to the exacting standards Barnes applies to military-contract ammunition—now available commercially to serious shooters.

The 220-grain OTM projectile features a boat-tail design and high ballistic coefficient, optimized for consistent flight and minimal wind drift at extended ranges. Barnes manufactures Precision Match to exceptionally tight tolerances, controlling standard deviation and velocity variation so that shot-to-shot performance is as consistent as ammunition can be. That consistency is what separates match ammunition from standard commercial rounds: tighter velocity spreads mean tighter shot groups, and tighter groups mean better wind calls and more forgiving holds at distance.

Each box includes a QR code linking to Doppler radar-generated drop tables specific to this load, giving you real, measured ballistic data rather than generic calculator estimates. That's the kind of data support serious long-range shooters rely on when dialing wind and elevation on paper or steel.

Frequently Asked Questions

What is 300 Win Mag ammunition used for?

The .300 Winchester Magnum is widely used for long-range hunting, precision rifle competition, and long-distance range shooting. It delivers high velocity and energy retention at extended distances, making it popular among hunters pursuing large game and competitors engaging targets at 600 yards and beyond.

What does OTM (Open Tip Match) mean?

OTM stands for Open Tip Match. The projectile has an open tip rather than a closed point, a design optimized for match-grade accuracy and consistent expansion behavior. It's distinct from traditional hunting ammunition and is built specifically for precision applications.

What information does the QR code provide?

The QR code on each box links to Doppler radar-generated drop tables specific to this load. These tables provide measured ballistic data for wind and elevation holds, giving you real-world trajectory information rather than estimates.

How many rounds are in a box?

Each box contains 20 rounds of Barnes Precision Match 300 Win Mag ammunition.
