Winchester USA White Box Features The Winchester USA White Box load is built around a 62 grain M855 green tip bullet that uses a steel penetrator tip under its full metal jacket to improve performance against harder targets compared to standard ball ammunition.

The result is a round that performs the same from the first shot to the last in the case giving shooters a dependable baseline to judge their rifle and their own technique against. Packaged as a 500 round case this Winchester USA load is built for shooters who go through ammunition quickly whether at a training class a club match or a weekend at the range with friends. Winchester backs this ammunition with the same quality control that has made USA White Box a trusted choice for decades of range use. The brass cased construction supports reloaders who want to recover and reuse components after shooting.
