On the heels of its .44 Mag. (1959) and 10/22 (1964) semi-automatic carbines, plus the classy No. 1 single-shot (1966), Ruger was still fairly new to the long-gun business when it introduced the Model 77 in 1968. From what was a modest launch—an economical ($160) short-action offered in .22-250 Rem., .243 Win., 6 mm Rem. and .308 Win.—the subsequent half-century of production has progressed through three distinct generational periods. During the run it has been rendered in scores of model variations spanning rimfire, center-fire and muzzleloader platforms, and nearly 60 different chamberings ranging from .17 HM2 to .458 Lott. Perhaps the Model 77 never quite caught up in terms of lore and overall sales to the Winchester Model 70 and Remington Model 700, but its history suggests that Ruger strived to outdo the big boys in its sheer number and variety of innovative applications.
