DIRECTIONS FOR PERSONS USING DETONATING 

 GUNS. 



LOAD with the cocks down. When ramming down 

 shot, observe the distance the end of the brass worm 

 is from the muzzle of the barrel, to prevent over- 

 charging. Always ram down hard. 



Prime the last thing ; otherwise, in ramming 

 down the wadding, the powder will be driven into 

 the caps, and become so firmly compressed as to 

 destroy their effect. 



Should the caps be put on by mistake prior to 

 loading, force them off with a turnscrew, and replace 

 them with new ones.
