By contrast, of the hundreds of factory and non-benchrest custom rifles I've tested over the years, only a skimpy handful have delivered even one group that small, usually quite by accident. Never mind those Internet chatterboxes who proclaim themselves possessors of hunting rifles that will print half-inch groups "all day long." The "gold standard" for a really accurate hunting rifle is one that will deliver 100-yard 5-shot groups that measure about 1 inch on a more-or-less regular basis. Among heavy-barreled varmint rifles, a true half-incher is a jewel. In either case, extremely good ammo is necessary for fine accuracy, which complicates matters considerably. The point here, however, is not to compare hunting sporters with expensive custom-made (figure $2,000 and up, plus a scope) benchrest rifles. It's to make clear how the rifles you now buy off a dealer's rack, the ammo on his shelf and even the very definition of accuracy have benefited greatly from developments first tried and proven by benchrest shooters.
