The XPR is an angular, streamlined bolt-action that incorporates a heavy, tubular receiver with a smallish ejection port, a massive, three-lug bolt, an extremely stiff synthetic stock, and a superb trigger. Winchester was very clever here. While the receiver is a circle in cross-section, which makes it rigid, the surfaces that are bedded are flat, which keeps it from twisting and squirming. This goes to the very heart of modern rifle accuracy: If you design in rigidity, concentricity, and lack of stress on any single component; if you make the rifle so it cannot twist, torque, bend, or flex, it’s going to shoot. Winchester did, and the XPR does.
