Do I really need the firing pin, or can I just use something pointy? Firing pins cost money my man. Also, instead of a .45 can I just use a .22? Also money.

I was thinking along those same lines, brother, but here are my thoughts.  I have never actually fired a round by striking the primer manually and therefore do not have any data to show that this is a sure bet, so I might have to use a firing pin.  The 45 is mostly a personal choice, but also the 45 would have a higher success rate if you flinched or something at the last moment. 
  
 Basically I figured better safe than sorry.
