Twin 50s:  These are as familiar armament to a PT as its fish.  The port and starboard turrets characterize the deadly sting that can be unleashed against air and surface targets.  They are sensitive guns and their machined parts must be well lubricated and kept free of corrosion.  The guns in a turret, like a team of horses, must function together in order to give accuracy of fire.  A 50 turret in good shape should not jam for long.  The essential points to remember are:

 

1. If it jams, charge it, charge it.  Do this at least twice before you even think of looking for serious trouble or stripping your gun.

 

2. Every gun has it peculiarities.  Learn them and make allowances.  When disassembling, keep each gun and its parts together rather than tossing them into a common stock pile.

 

3. Ammunition must be clean and well covered.  Protect it against dirt and water.  Oiled or greased cartridges should not be fired.  Oil or grease causes the collection of dust and other abrasives which may be injurious to the gun and also may result in hazardous chamber pressures.  Dust, dirt, fibers, and even hair may cause your gun to jam.  Salt water corrodes the cases and moisture can make your primers useless.
