I think we have an answer to what the “Flat End” Lesmoke .22 L.R. round cataloged in the 1913-14 and 1915-16 catalogs is.
I am inclined to think that this “Gully” cartridge is the “Flat End Bullet” in the listing. The years are right for both the Patent Date and for the box shown. Plus the wording “flat across its forward end” in the patent description fits with the catalog description. It is cataloged as a “Lesmoke” cartridge, which again agrees with the box.
The following box was posted on AA for sale by Dick Fraser
Here is a rare, probably experimental, loading of the Gully patent bullet by Remington. This auction is for one loaded round. On December 29, 1914 US patent number 1,122,738, “TARGET-BULLET”, was issued to Albert B. Gully of Bridgeport, Connecticut, assignor to Union Metallic Cartridge Company. Quoting from the patent, its object was for a “non-jacketed bullet especially adapted for short range target shooting…which, owing to special details of construction…will produce better targets than has been possible with any bullet heretofore produced, will not tear the target but will cut a round hole therein, will be self-centering in the bore of a gun barrel should it happen to be loose in the cartridge shell and will effectively clean the grooves of the bore and keep them clean.” The bullet “tip tapers slightly…is provided with a central recess or cavity having an inclined wall…[color=#FF0000]is flat across its forward end[/color]…the diameter at the forward end corresponds substantially with the diameter of the gun barrel…”. “Pressure must be applied to the rear end of the cartridge to force the tip of the bullet into the bore…to cause the lands of the bore to form corresponding grooves in the bullet.” “When the bullet is fired, the effect of the resistance of the air owing to the recess in the tip is to expand the tip outward so that still deeper grooves are formed in the bullet.”
Now if we could just identify exactly what the “Life Target Gallery” cartridges are!!
