Dont know if this qualifies as an extreme sport but.....

This is what I do in my spare time. I compete in IPSC matches. For those that never heard of it, it is what practical shooting has evolved into. If youve watched Top Shot, the guys that compete in the USPSA do this shooting. Here's a video that I took Wednesday night during practice. Im  shooting in a local match tomorrow and plan on taking some more footage during the match.
