CARTRIDGE SA 12 BORE 70MM “ASTRAM”

This ammunition is fired from a 70 mm Chamber 12 Bore Gun. This cartridge is an improvement on our existing popular brand “Special” Paper cartridges in so far as their construction and performance characteristics are concerned. The body is made up of high density polyethylene plastic tubes, bi-axially oriented, to withstand higher pressures and achieve higher velocity in place of paper crimson. The use of LDPE Power Piston with pouch in place of paper air-cushion as used in “Special” cartridges, not only provides better gas sealing but also results in achievement of higher accuracy in firing giving a very good pattern of shots. The cartridges use non-corrosive caps along with tubular anvils which eliminates occurrence of misfires. The use of smokeless propellant power give no smoke after firing and the use of hardened lead shots give a good impact on the target. The above improved characteristics make these cartridges suitable not only for use in general hunting, etc. but also for “competition shooting”. Our “Astram” cartridges have already found great favour with many renowned shooters in the competition shooting games.

Cartridges are packed in multi-coloured and attractive laminated cartons. 25 cartridges are packed in one carton. A lot of 20 cartons holding 500 cartridges or a lot of 10 cartons holding 250 cartridges are first put in polythene bags and then heat sealed to avoid ingress of moisture. These polythene bags with 50 or 25 cartons are then packed in wooden boxes or pre-printed corrugated fibre board boxes respectively and duly strapped with steel or plastic tapes. The packing is quite secure and lasting.
