GUNSAFETYWARNINGS IT IS ESSENTIAL THAT THESE OPERATING INSTRUCTIONS BE THOROUGHLY STUD- IED BEFORE USING THIS FIREARM TO ASSURE PROPER AND SAFE GUN HAN- DLING. FAILURE TO FOLLOW THESE INSTRUCTIONS OR FAILURE TO OBEY ANY SAFETY WARNING MAY RESULT IN INJURY TO YOURSELF OR OTHERS, OR CAUSE DAMAGE TO YOUR GUN. As a gun owner, you accept a set of demanding responsibilities. How seriously you take these respon- sibilities can be the difference between life and death. There is no excuse for careless or abusive handling of any firearm. At all times handle your rifle and any other firearm with intense respect for its power and potential danger. PLEASE READ AND UNDERSTAND ALL OF THE CAUTIONS, PROPER HANDLING PRO- CEDURES AND INSTRUCTIONS OUTLINED IN THIS BOOKLET BEFORE USING YOUR NEW FIREARM. 1. Do not carry a loaded gun with a live round in the chamber while walking, running, climbing a tree, crossing a fence or anywhere you might slip or fall, drop the gun or otherwise bump or jar the gun. A gun that is dropped, bumped, or jarred with a chambered round might accidentally discharge even with the safety on, causing serious injury to you or someone else. When a round is chambered keep the safety on until you are ready to shoot. 2. Do not rely on the safety to prevent accidental dis- charge. Many safeties merely block the trigger and prevent firing by pulling the trigger. The safety may not prevent an accidental discharge due to dropping, 3 MODEL52B BOLTACTION22 RIMFIRE The Model 52 is what legends are made of. Your Model 52B offers the accuracy you want in a rimfire bolt action. It has the renowned Micro Motion trig- ger system. Producing a trigger system like this is labor intensive and requires extraordinary precision. Watch-like part fits like you see in a 52B are rare in these modern days. The match chamber adds further to the 52Õs exceptional accuracy. You may have already noticed how smooth and effortless it is to work the bolt. The magazine system, with its five shot capacity, is easy to operate and very reliable . . . just like on the originals. The history behind the Model 52 is equally extraordi- nary. It first appeared in 1919 and was shot at the National Rifle Matches that very year. It was a favorite of returning veterans after World War I because of its bolt action design that utilized a remov- able magazine. Many consider it one of the most sig- nificant factors in the growth of small-bore target shooting in the United States. 2
ous injury in case of an accidental discharge. Never load in the house or in your vehicle. 12. Never shoot at a hard, flat surface or at the sur- face of water to avoid a ricochet and possible serious personal injury to yourself or a bystander. 13. Store your gun in a clean, dry place out of the reach of children and separated from stored ammuni- tion. 14. Never alter any parts of your gun. Any alterations or adjustments that may become necessary to the operating mechanism should be performed by a quali- fied gunsmith. 15. Hunting from elevated surfaces such as tree stands is dangerous. Doing so may increase the risk of han- dling any firearm. Always make certain that the stand being used is safe, sturdy and stable. Always make certain your firearm is unloaded when it is being taken up and down from the stand. Always make cer- tain that your firearm is not dropped from the stand or dropped while it is being taken up or down from the stand. 16. Discharging firearms in poorly ventilated areas, cleaning firearms, or handling ammunition may result in exposure to lead and other substances known to cause birth defects, reproductive harm and other serious physical injury. Have adequate ventilation at all times. Wash hands thoroughly after exposure. 5 jarring, or bumping a gun. 3. Use only ammunition for which the gun is cham- bered as indicated on the barrel, to prevent excessive pressure and possible serious personal injury. 4. Incorrectly reloaded ammunition can cause serious personal injury and damage to the firearm due to excessive pressure. Reload only after proper instruc- tion and in strict compliance with instruction and data contained in current reloading manuals. 5. Never point a gun at anything you do not intend to shoot. Always keep it pointed in a safe direction in case of accidental discharge. 6. Always check to ensure that the barrel is free of obstructions before loading and using the gun. If you experience light recoil or off sound, check the barrel for an obstruction. 7. Before firing, clean any grease or oil out of barrel with cleaning rod and patch. Grease or heavy accu- mulation of oil can cause excessive pressure and result in serious personal injury. 8. Keep barrel, chamber and action free of rust. Rust in the barrel and chamber can cause excessive pres- sures resulting in serious injury. A rusted, pitted or eroded barrel should be replaced. 9. Use hearing protection to prevent ear damage from repeated exposure to gunfire. 10. Always use proper shooting glasses to prevent eye injury from flying particles. 11. Never carry a loaded gun in a motor vehicle or carry one into a dwelling. Always carefully unload the gun before entering a motor vehicle, a dwelling or an area such as a camp. Always point a gun in a safe direction while loading or unloading to prevent seri- 4
7 FIGURE1 The heart of the Model 52B is its incredible trigger system. Over the years the name ÒMicro Motion TriggerÓ has become syn- onymous with accuracy. The rear of the receiver is drilled and tapped for mounting a peep sight. The plain barrel can be fitted with a front sight by a gunsmith, if you so desire. The in-line, curved magazine offers reliable feeds. The button on the right side releases the magazine for re-filling.Low profile swivel attach- ments just like early versions of half a century ago. The magazine release button is conveniently placed on the side of the stock, just below the ejection port. The forearm adjustment screw lets you apply pressure or force against the underside of the barrel in order to maximize accuracy. 6 MODEL52B FEATURES The stock is of beautifully fin- ished selected walnut, careful- ly cut checkered. FIGURE1 The receiver top is drilled and tapped for scope mounts. This is a rifle with accuracy truly worthy of the finest scopes. The Model 52BÕs Micro Motion trigger system is famous for its smooth, crisp let-off. The thumb-operated safety is con- veniently located on the right side of the receiver, just forward of the bolt handle. A cocking indicator on the rear end of the bolt makes it easy to deter- mine your rifles cocking status.
The Model 52B comes with the receiver drilled and tapped to accept commercially available rear peep sights and scope mounts. A two-piece scope mount base and high scope mount rings are available as ac- cessories. (Front sights must be installed by a quali- fied gunsmith.) TERMINOLOGY ANDDESCRIPTIONS Descriptions in this booklet generally refer to the gun in the horizontal position. That is, in the normal fir- ing position. For example, the muzzle is forward or front; the butt stock is rearward or rear; the trigger is downward or underneath; the sights are upward or on top. Figure 1 covers the general features and benefits of the Model 52B design. For general parts terminology, refer to Figure 2A and 2B. With the exception of magazine disassembly, fig- ure 2A also shows the Model 52B disassembled to the extent necessary in order to follow instructions con- tained in this book. Throughout this manual the ÒactionÓ refers to the 9 FIGURE2A Muzzle Fore-endFore-end tip Barrel GENERALDESCRIPTION Your new Winchester Model 52B is a reproduction of the original Model 52B ÒSportingÓ bolt action. It fea- tures the highly regarded trigger system. Other fea- tures of the Model 52B include the side safety, the black forearm tip, the special quick-release swivel mounts on the forearm and stock, and the conve- nient five-shot removable magazine (additional spare magazines can be purchased from your Winchester firearms dealer). 8 FIGURE2A Magazine Buttplate Ejection Port Trigger Buttstock ReceiverBolt Safety Extractor Cocking indicator Magazine release button Bolt Bolt handle FIGURE2B
GENERALOPERATION The Model 52B is a bolt action rifle that operates by lifting the bolt handle, drawing the bolt rearward and then sliding the bolt forward and rotating the bolt downward until it locks into battery position. This process takes a cartridge from the magazine and loads it into the chamber for firing. CAREFULLY READ THE FOLLOWING PRO- CEDURES BEFORE ATTEMPTING TO SHOOT YOUR MODEL 52B RIFLE. INITIALCLEANING BEFORE THE FIRST FIRING, CLEAN THE BORE WITH A CLEANING ROD & PATCH. ALSO, CLEAN THE ANTI-RUST COM- POUND FROM THE INSIDE OF THE RE- CEIVER WITH A CLEAN RAG AND LIGHT GUN OIL. SEE ÒCARE AND CLEANINGÓ LATER IN THIS MANUAL. OILING THE ACTION Before the first firing you should wipe the mechanism completely clean, clean the bore and apply a few drops of oil on the following surfaces: ¥ Along the breech bolt surface and where the sleeve contacts the breech bolt. ¥ Along the breech bolt surfaces on the receiver where the bolt contacts the receiver as it is worked. Avoid applying too much oil. Only a light film is necessary. Cleaning and Maintenance Suggestions should be followed before each oiling. 11 mechanism of this rifle which loads and secures the cartridges in the chamber. SERIALNUMBER The serial number can be found on the right hand side of the receiver. Record the serial number at the front of this book for future reference. AMMUNITION The caliber of your Model 52B is inscribed on left side of the barrel, toward the receiver. The Model 52B must be used only with .22 Long Rifle cartridges. It is unsafe to attempt loading mag- num cartridges in a rifle designed for Long Rifle car- tridges. U.S. Repeating Arms Co. can assume no responsibili- ty for incidents which occur through use of cartridges of nonstandard dimension or those developing pres- sures in excess of SAAMI (Sporting Arms and Ammunition ManufacturerÕs Institute) established standards. Winchester ammunition is always an excellent choice for your new Winchester rifle, delivering the unmatched performance and dependability you want. DISCHARGING FIREARMS IN POORLY VENTILATED AREAS, CLEANING FIREARMS, OR HANDLING AMMUNITION MAY RESULT IN EXPOSURE TO LEAD AND OTHER SUBSTANCES KNOWN TO CAUSE BIRTH DEFECTS, REPRODUCTIVE HARM AND OTHER SERIOUS PHYSICAL INJURY. HAVE ADEQUATE VENTILATION AT ALL TIMES. WASH HANDS THOROUGHLY AFTER EXPOSURE. 10
INSERTING ANDREMOVING THEBOLT INSERTING THE BOLTÑ The Model 52 rifle comes packaged with the bolt re- moved from the rifle. It is necessary to insert the bolt into the receiver. WARNING: REMOVE THE MAGAZINE AND MAKE SURE THE RIFLE IS FULLY UN- LOADED BEFORE PROCEEDING. To insert the bolt the safety must be placed in the Òoff safeÕÕposition. 1. The front and rear portions of the bolt must be aligned properly before it can be inserted. The bolt handle (and connected locking surface) can rotate with respect to the bolt body itself. If not already in alignment the parts must be realigned. To do this: a)Take the end of the bolt body in one hand and the bolt handle in the other. b)Twist the handle to align the top and bottom pointers on the shroud with the grooves cut in the bolt. The top groove is on the polished por- 13 Cocking indicator FIGURE4 Extends rearward when the bolt is cocked OPERATION OF THESAFETY The safety is located on the right side of the receiver (Figure 3). When the safety is clicked (or is detented) into position toward the rear, the gun is in the Òon safeÕÕ position as shown. In this position the trigger is blocked. ÒSafeÓ is stamped on the receiver to mark this Òon safeÓ position . WHENEVER A CARTRIDGE IS CHAM- BERED, THE SAFETY SHOULD BE MOVED TO THE ÒON SAFEÕÕ POSITION UNTIL YOU ARE READY TO FIRE IT. When the safety is pushed forward, the rifle is in the Òoff safeÕÕ position and ready to fire. COCKINGINDICATOR The rear end (or shroud) of the bolt serves as a cock- ing indicator. When the bolt is in the rifle and is cocked the indicator will appear (see Figure 4) Ñ ex- tending rearward forming a gap between the pointed surface on the indicator and the pointed recess on the bolt (Note: there is a pointed surface on top and bot- tom of the shroud). When the rifle is fired, the cock- ing indicator (entire shroud) moves forward, closing the gap. 12 Safety FIGURE3 Pull fully rearward to place in Òon safeÓ position Push forward foroff safe
5. Return the safety to the ÒOn SafeÓ position. The rifle is now assembled and may be operated normally. REMOVING THE BOLTÑ BEFORE REMOVING THE BOLT FULLY UNLOAD YOUR RIFLE: REMOVE THE MAGAZINE FROM THE RIFLE AND OPEN THE BOLT. VISUALLY ASSURE THAT THE CHAMBER IS EMPTY. 1. The firing mechanism must be uncocked before the bolt can be removed. With the rifle fully unload- ed and pointed in a safe direction, close the bolt, then uncock the bolt by dry firing the rifle. 2. With the bolt now uncocked, insert your finger 15 Pull the trigger and then push the bolt into place. It may take a little force. FIGURE7 Pull the trigger, push the bolt and depress the sear. FIGURE8 Inserting the bolt, option 2.Inserting the bolt, option 1. tion of the top lug (see Figure 5). The bottom groove is on the rear of the bottom lug. 2. Align the end of the bolt in the rear opening of the receiver as shown (see Figure 6). 3. While pulling the trigger, push the bolt forward and shove it in the receiver, past the point where it is stopped by the sear (see Figure 7). This may take a little force, but not too much. Optional: The sear can be depressed with a screwdriver for easier insertion (see Figure 8). This makes it much easier to insert the bolt. 4. Release the trigger and rotate the bolt handle down to lock it. CAUTION: The chamber should be empty Ñ if there is a round in the chamber, the rifle can be fired if the trigger is pulled. 14 Orient the bolt flat side down before inserting. FIGURE6 Aligning the bolt FIGURE5 Front and rear parts of the bolt must be in alignment before inserting into receiver. The small points must align with the small grooves on the shroud and lug.
