Step 3: WEAPONS
the shotgun is entirely different case , its shells are heavy when your carrying hundreds of those , but its head splattering capacity is unbeatable , so its good when the time comes.
semi automatic rifle (ex. mauser 98k , or any good old 7mm) are the best for range, accuracy, kill ratio,and head-splattering action. The pistol is should and only be used as a back-up weapon, theirs multiple reasons ,like the fact its hard to aim,low magizine capacity and the fact it sucks at range, makes the pistol as crappity as crap gets.
