USA Ready Winchester Small Rifle Match Primers
The primers used in match-grade Winchester USA Ready ammunition are the same as those used in Winchester Match Primers. For uniformity from shot to shot, these primers are constructed to stringent standards. All primers are extensively and continuously tested for consistency and sensitivity under situations and at temperatures well outside their typical operating range. Winchester promises improved sensitivity for more positive firing in all firearms, weights of primer combinations that are carefully regulated, uniformity in size and quality, exact measurements and tolerances for anvil heights, and stability in the face of fluctuations in temperature and humidity.
