“R e-sizing.”—The cases should be slightly oiled, placed in the cylinder, 
the plug driven down with the mallet as far as the shoulder ; the concave end 
of the plug is for knocking the case out of the cylinder, and it is then ready for 
re-capping. 
The barrels must be thoroughly cleansed of oil before shooting, otherwise 
the first few shots will be defective. 
PRESSURES AND VELOCITIES. 
The following table shows the result of trials by The Field of the pressure 
and velocity of express black powder cartridges and cordite cartridges. 
The Field says :—“ Our trials have conclusively proved that for any given 
velocity and weight of bullets, cordite gives Lower Chamber Pressures than 
Black Powder. 
“ Subjecting the cartridges to moderately-increased temperature does not 
appear to lead in the direction of danger, although, of course, no one would allow 
his cartridges to be exposed to the sun’s rays in hot climates. Pushing the bullet 
into the case, and thus reducing the air-space, generally results in considerably 
increased pressure. Had the cases been recrimped after pushing in the bullets, 
the pressures would have been still greater. We emphasize this fact as a warn¬ 
ing to those sportsmen who load their own cartridges.
