  • 26. PRIMER
    RIFLE AND PISTOL PRIMERS ARE SMALL METAL CUPS CONTAINING PRIMING MIXTURE AND AN ANVIL
  • 27. PRIMER
    THE BLOW OF FIRING PIN ON THE PRIMER CUP CRUSHES THE PRIMINGMIXTURE AGAINST THE ANVIL CENTER AND BURNS IT ,WHICH THEN FLASHES THROUGHT THE FLASHHOLES AND BURNS THE POWDER
  • 28. PRIMER
    IN RIFLE CARTRIDGE PRIMERCUP IS FITTED IN BATTERY CUP.
    THE BATTERY CUP SUPPORTS THE ANVIL AND PROVIDES FLASH HOLES
  • 29. GUN POWDER
    • BLACK POWDER
    • 30. SMOKELESS POWDER
  • BLACK POWDER
    • POTASSIUM NITRATE 75%
    • 31. SULPHUR 10%
    • 32. CHARCOAL 15%
  • BLACK POWDER

    • 34. IT BURNS WITH PRODUCTION OF HEAT ,FLAME AND SMOKE
    • 35. 1 GRAM OF POWDER PRODUCES 3000 TO 4500 CC OF GAS
  • SMOKELESS POWDER
    • THEY PRODUCE MUCH LESS SMOKE AND FLAME AND ARE MORE COMPLETELY BURNT THAN BLACK POWDER
    • 36. 1 GRAM PRODUCES 12000 TO 13000 CC OF GASES
    • 37. THE COLOUR VARIES FROM BRIGHT ORANGE TO BLUISH BLACK
