QUALITY :
All components, going into the cartridge, go through strict quality checks and no deviation from the laid down parameters is permitted. Important Constituents of the cartridge like the cases, propellant and the percussion, caps are proof tested before use in the manufacture of the cartridges. The manufacture of the cartridge in automatic loading machines in controlled atmosphere ensures uniform and highly consistent quality in the cartridges. Finished cartridges are subjected to 100% visual inspection to weed out defectives. Gauging of the cartg lots is done as per sample plan and proof firing is conducted on the finished cartg lots to ensure quality of performance for the cartridges for velocity, accuracy and pressure as per IS -2500.

Cartridges, so found acceptable after such stringent inspection schedule are only released in the market. No doubt, therefore most customers prefer our cartridges only.
 
SAFETY :

The design and construction of our cartridges make it extremely safe to handle. Cap percussions, which pass through strict sensitivity and insensitivity tests are so assembled in the case that even rough handling do not activate the cartridges. The star crimping of the case ensure positive sealing of the cases and thus ensure complete protection of propellant from outside influence.
 
RELIABILITY :
Strict quality checks and final performance proof on the finished cartridge lots as per laid down norms ensure high level of quality in our cartridges.
 
SHELF LIFE :
The shelf life of the special cartridges is maximum 5 years.
 
PACKING :
Our cartridges are packed in multicolored and attractive laminated cartons. 25 cartridges are packed in one carton.
