® The RUGER MODEL 77/50 is a muzzleloading, percussion rifle intended for use with black powder, percussion caps, soft lead and jacketed “saboted” projectiles. It has a precision rifled barrel with a 1-in-28” rifling twist. It does not fire conventional cartridges, but is instead loaded from the muzzle of the barrel. It is of bolt-action operation, and must be cocked and capped by opening the bolt, placing a cap on the nipple, and then closing the bolt before normally firing the rifle by pulling

OPERATION OF SAFETY ® The RUGER MODEL 77/50 rifle has a three position safety. The safety selector is located at the right of the bolt sleeve. The safety selector can be moved from the “Fire” position to its two other positions (“Load-Unload” and “Safe”) only when the striker is cocked. Fully raising the bolt handle cocks the striker. The bolt handle can be raised and lowered only when the safety selector is in either the full forward “Fire” or the middle “Load-Unload” position. When the safety

WARNING –MANUAL SAFETY ! Keep the safety on unless actually firing. Always 3 FIRE move the safety fully to its intended position and check it. The safety has three positions –“SAFE,” “LOAD-UNLOAD,” and “FIRE.” Never depend on a safety mechanism or any other mechanical device 2 to justify careless handling or permitting the rifle to point in an unsafe direction. The only “safe” LOAD- UNLOAD rifle is one in which the bolt is open, the barrel is empty of both powder and projectile, and the nipple i

Black Powder is usually classified by powder grain size, with “Fg” being the largest granulation and “FFFFg” being the smallest granulation normally available. Use only “FFg” (sometimes called “2F”) grain size black powder in the ® RUGER MODEL 77/50 rifle. Replica Black Powder such as Pyrodex RS may be used, so long as suggested loading data is strictly adhered to. Note that Pyrodex RS is less dense than FFg black powder and must only be used as a measure-for-measure substitute for FFg black pow

Never load multiple projectiles into the barrel. The rearmost projectile slamming into the other projectiles when fired could cause a burst barrel and severe personal injury. Use only one bullet at a time. SABOTS Some projectiles designed for

INSERTING THE BOLT 1. Be certain the barrel is empty by pointing the muzzle upward towards a light source and glancing through the rear of the action at the rear end of the nipple. You should see light through the hole in the nipple, indicating that the barrel is empty. Keep the muzzle pointed in a safe direction, and keep your fingers off the trigger throughout the assembly and loading process until you are actually ready to fire. (See Rule 2, p. 43). 2. Position the safety selector in the “Loa

WARNING –LOADING ! Know the bore diameter of your rifle you are loading and load projectiles of only correct diameter into it! Either a too tight or too loose projectile can cause a burst barrel, resulting in serious injury to the shooter or bystanders. This rifle is designed to use a .500” projectile (or a .490” projectile with a .010 - .015” thick patch), a #11 percussion cap, and up to a maximum of 120 grains of ? FFg black powder (or equivalent volume of Pyrodex RS) only. Never use smokeless

WARNING –HANDLING ! If this rifle is to be carried loaded, certain precautions must be observed in the interest of safety. It is safest to carry any muzzleloader with no percussion cap on the nipple.

Best results are obtained by cleaning the bore after each shot, before reloading. Soak a patch in black powder solvent or bore lubricant, place it over the front end of the ramrod, push it completely into the bore, and pull it completely out of the muzzle. If it is difficult to remove, push the patch back down and then up until it can be removed. This “swabbing” after each shot makes reloading much easier. Never try to reload another projectile if it is excessively difficult to push down the bar

y t e TO UNLOAD (Keep rifle pointed in a safe direction) Completely unload the rifle immediately when you are finished shooting (by removing cap, powder and ball), or fire it into a safe backstop. It is much easier and safer to fire any muzzleloading firearm rather than attempt to unload it. However, if this is impossible, or if you are uncertain that correct components have been safely loaded, the rifle should be unloaded in accordance with the following steps. 1. Be sure the rifle is pointing
