Ruger is now selling a Model 77 chambered in .357 Magnum. The 77/357 feeds from a 5 round flush rotary magazine.
Bruce Rozum, Chief Rifle Engineer at Ruger, says …
“The 77/357 is an effective tool for hunting medium-sized game – especially in heavy cover. Bullet velocities of .357 Magnum ammunition increase significantly when fired out of the 77/357′s 18 1/2″ cold hammer-forged barrel. In testing, Hornady® 140 grain FTX® loads were clocked at over 1820 feet per second. Furthermore, the flush-fit, five-shot rotary magazine does not protrude at the rifle’s balance point and, unlike tube-fed rifles, the Ruger 77/357 can be readily loaded and unloaded” .
