Abbreviations Here

[spricks]

While they are the norm here for folks that know what they are talking about....is it possible for someone to list the common ones used here with their meanings?
If possible...Thanks in advance.

Thanks for the help Ken. I'm confused with the shooting sports abbreviations like IDPA...etc...How many different ones are there? Seems like up North here it's not even common knowledge. Is that because indoor ranges are few and far between up here. Sorry for being stupid on this issue!
