POWDER 75 



Eley's of London, where millions of cartridges are 

 annually loaded, or in those gun-makers' establishments 

 where hundreds of thousands are turned out year by 

 year. Electricity, or other power, has been usefully 

 harnessed to the work of turning in the cases, and these 

 turnover machines, running, in many instances, at a 

 speed of 1000 or more revolutions per minute, thereby 

 accomplish the work with an evenness and nicety of 

 finish not previously attained. 



Sporting explosives of the day may be classified 

 under four heads 



1. The black gunpowders, of which the "Diamond 

 Grain" of Messrs. Curtis and Harvey and the "Nonpareil " 

 of Messrs. Kynoch are probably the most familiar and 

 reliable examples. 



2. The so-called " bulk " nitro-compounds, a not too 

 explicit title, psrhaps, which comprises those bulking 

 the same as black gunpowder. That is to say, a 

 3-dr. measure of these nitros will occupy the same 

 space in a 12-bore cartridge as does black powder. 

 At the same time, the weight of these powders is 

 practically half that of black, or somewhere about 

 41 grains for the 3-dr. charge. 



3. Is a group of nitros intermediate, as regards weight, 

 betwixt the bulk and the concentrated classes. To 

 this class, for lack of more specific title, the term "33- 

 grain nitro " has been applied. This, by reason of the 

 fact that whilst filling the cartridge-case to the same 

 extent as the bulk powders, their weight is, practically, 

 33 grs. for the 3-dr. measure. 



4. Includes the concentrated or condensed section 

 of nitros, a class independent of the rest, in so far 

 as measurement and weight of charge is concerned.
