Barnes Precision Match .300 Winchester Magnum ammunition (part no. 30740) loads a 220-grain Open Tip Match boat-tail bullet built for shooters who need to send it with confidence at extended range. Barnes pairs a temperature-stable propellant with first-quality, premium brass to hold extreme spreads and standard deviations low, the numbers that separate a match load from a hunting load. The Open Tip Match design is a precision bullet, not a hunting expansion bullet, built for consistent flight and repeatable accuracy shot after shot rather than terminal performance on game. For long-range shooters chambered in .300 Winchester Magnum, this is rifle ammunition built to remove ammunition as a variable.
