The Hornady Outfitter Rifle Ammo 300 Wby. Mag. 180 gr. CX OTF 20 rd. delivers a practical, field-ready solution for hunters who need reliable terminal performance in wet, abrasive environments, and the Outfitter series is built around Hornadys CX (Copper alloy eXpanding) monolithic hunting bullet that provides uniform, controlled expansion and exceptional weight retention for deeper penetration through heavy muscle and bone, making it a go-to choice for big game like elk and moose at extended ranges. With a 180?grain CX bullet launching at about 3100 fps and producing roughly 3841 ft?lbs of muzzle energy, this load balances flat trajectories and downrange energy for long-range shots from mountain blinds or treestands. The waterproofed nickel?plated cases resist corrosion and moisture for reliable feeding and storage in backcountry packs or wet climates, and the cartridge is California compatible for areas that require nontraditional bullets. If you hunt in coastal, riverine, or high?humidity regions and want a high?velocity 300 Weatherby Magnum load with superior penetration, consistent expansion, and dependable performance, the Hornady Outfitter CX is engineered to meet those needs.
