BB's

  For an informative post, it has come to my attention that using heavier weight bb's (say .25 or .28) actually travel farther than lighter weight bb's ( say .12 or .2).  Common misconception is that lighter bb's travel faster because when chrono'd using light weight bb's the fps number is higher than say using .28s. This is entirely false however because light weight bb's lose all that initial speed soon after exiting the barrel, while heavier bb's keep more of it. 
  When firing at a target greater than 60', it is better to use a heavier bb because of inertia, the bb will keep more of its speed for longer making the heavier bb more accurate.  For distances less than 50', using .2s are fine, such as in a Close Quarters game where spray and pray makes accuracy not mater.  Now, I'm not telling you to go buy .25s for your clear/crappy sports store gun, .25s and .28s are best used in good quality AEGs that can fire above 340 fps.  For any gun below 300 fps...it is best to stick to .2s or .23s.
