 done no emery polishing is necessary. 



Where a large amount of boring is done, a faster 

 cutting bit with serrated edges is sometimes used in 

 the first part of the work. 



Now it sometimes happens that the gun will be 

 found to shoot to one side, too high, or too low, 

 especially after poor boring. Don't be alarmed and 

 think that the barrels must be taken apart and read- 

 justed, as you are very likely to be told ; all that is 

 necessary is to scrape out a very little from the proper 

 side of the choke near the muzzle, and the fault is 

 corrected. 



You will perceive too, a great difference in the ex- 

 tent of the spread of various sized shot ; so, either 

 bore your gun to shoot right with the size you wish to 

 use, or use the size that is found by actual test to best

 shot, for with small ones any full choke will shoot 

 close enough. 



To obtain the very closest shooting, the muzzle of 

 the gun should be cleaned after each discharge, 

 and this must always be done at the boring trials 

 when such a gun is desired. For duck shooting,
