Winchester S300SBC 300WSM 195GR BC MAX 20/10

The Winchester S300SBC 300WSM 195gr BC MAX ammunition is built for hunters who refuse to compromise on range capability. This 300 Winchester Short Magnum load pairs a heavy-for-caliber 195-grain bullet with BC MAX technology—Winchester's latest advancement in precision rifle ammunition—to deliver extended effective distance and consistent accuracy on demanding hunts. Whether you're setting up for a mountain elk at 400 yards or pushing beyond, this round is engineered to perform when conditions and distance separate success from regret.

Winchester designed BC MAX bullets with a large-diameter tip that initiates positive expansion while an extended boattail profile and heat-resistant tip work together to maximize ballistic coefficient. That means less wind drift, flatter trajectory, and predictable flight through real-world hunting scenarios. The precision-drawn, thick-walled jacket supports both the aerodynamic efficiency and the terminal performance required for clean, ethical kills at extended range.

Inside every cartridge you'll find a match-grade primer built to Winchester's exacting specifications, delivering the shot-to-shot consistency that serious long-range hunters demand. The ammunition is loaded on next-generation assembly equipment designed to hold industry-leading tolerances, so each round shoots like the last. This is ammunition for the shooter who respects distance and understands that consistency at the bench translates to confidence in the field.

Each box contains 20 rounds in a 10-box case pack, making it practical for both practice and hunting. If you're running a 300 WSM and want a modern long-range round that combines ballistic efficiency with terminal authority, this is serious ammunition.

Frequently Asked Questions

What is BC MAX ammunition and how does it improve long-range performance?

BC MAX is Winchester's precision rifle bullet technology combining an extended boattail, heat-resistant tip, and optimized nose profile to maximize ballistic coefficient. The higher BC reduces wind drift and maintains velocity over distance, delivering flatter trajectories and more consistent impact points at extended range.

Is this ammunition suitable for hunting at extreme distances?

Yes. The 300WSM with a heavy 195-grain BC MAX bullet is specifically engineered for long-range hunting. The combination of ballistic efficiency and terminal performance supports ethical hunting decisions at distances where wind and bullet drop become significant factors.

What comes in each box and case?

Each box contains 20 rounds of loaded ammunition. The case pack includes 10 boxes, for a total of 200 rounds per case order.

How does the match-grade primer affect accuracy and consistency?

Match-grade primers are manufactured to tighter tolerances than standard primers, which reduces variation in ignition timing and pressure curve. This translates to lower velocity spread between shots, which is critical for achieving the repeatability needed for accurate long-range shooting.
