WINCHESTER REPEATING ARMS COMPANY  AND OTHER MAKERS FACTORY SHOP FUNCTION CARTRIDGES – INERT ROUNDS FOR TESTING FIREARM FUNCTIONS AT THE GUNSMITH’S BENCH – SETS AND INDIVIDUAL CARTRIDGES – SCARCE OFFERING:  Manufactured by Winchester and other makers, and intended for use by their gunsmiths and on their arms production floors, these “Factory Shop Function Cartridges” were never intended for sale to the general public.   

Produced for every caliber needed by the gunsmiths, these inert cartridges were manufactured without any gun powder and the primers were not only empty, but in many cases were also drilled to prevent an accident in the shop.  To take the safety measures one step further, some of the shop function cartridges were drilled through the side walls.  To further identify them as inert, and to provide a ready visual difference between these function cartridges and a standard live cartridge, many of these function cartridges were coated with a unique finishes in dark bronze, or metallic red and blue.  Each cartridge bears the standard headstamp for that particular caliber.   

The centerfire function cartridges were made in two different patterns – those with the standard cartridge head with the primer pocket, and a flat base with no primer pocket.  While the flat based cartridges have an appearance much like a rim fire or an early internally primed cartridge, they are headstamped with the centerfire caliber identification and all of them were cartridges developed after external primers became standard.  I have not been able to determine the reason for the difference, but perhaps it is a function of the period in which they were made, the flat base specimens being older. 

These are relatively scarce offerings from an old, well established collection and when these are sold I do not anticipate having any others.  I have the following sets and individual pieces in stock, each described below with accompanying photographs.   

 

NO. 1  FACTORY INERT SHOP FUNCTION CARTRIDGES – 9 PIECE SET:  This set includes a range of factory shop function cartridges from .300 Weatherby Magnum to .44-40 Winchester.  Each cartridge is in very good to excellent condition, retaining the original factory applied bronze finish, the factory loaded bullet, and a clear legible headstamp.  The full listing of the cartridges can be seen in the photograph below of the cartridge headstamps.  (0825)  $60

NO. 7  WRA FACTORY SHOP FUNCTION CARTRIDGE - .32 AUTOMATIC COLT PISTOL (.32 ACP) – SCARCE “WOOD ROD DUMMY”:  Another of the Winchester factory produced shop function rounds, this cartridge incorporated a wood rod loaded under the bullet which ran the full length of the inside of the cartridge case, hence the name.  The wooden rod is not visible, however the sides of the cartridge case are drilled as with other shop function rounds in order to preclude them from being loaded and to readily identify them as inert.  The wooden rod can be felt by inserting a paper clip-sized wire through the holes.  I suspect the rod was intended to keep the bullet at the proper seating depth.  The cartridge is the standard brass color and the primer bears the Winchester “W”, leading me to believe this cartridge pre-dates the dark bronze finished shop function cartridges.  This is another interesting Winchester product, and one that would be an interesting addition to a Colt Pistol collection as well.  (0512)  $15

 

NO. 8  UNION METALLIC CARTRIDGE COMPANY FACTORY SHOP FUNCTION CARTRIDGE – .30 REMINGTON:  This UMC factory shop function cartridge is headstamped .30 Remington, dating the production of this piece between the introduction of this caliber in 1906 and the merger of the UMC and Remington Arms in 1912.  Likely far scarcer than the Winchester Shop Function Rounds, this UMC piece is in excellent condition, retaining the original factory applied nickel plating, the factory loaded bullet, and a clear legible headstamp.  This is a very nice example of the shop function cartridges in use in factories and gunsmith shops at the turn of the 20th Century.  (0765)  $15
