So I'm getting really rusty with my shooting. Would like to participate in another competitive sport while being able to practice indoors.

I want to keep it under 800 dollars for the whole deal; cheap offhand glove, cheap ISSF legal jacket, used rifle and pellets. I'll save up later for a stand and spotting glass.

Basically I don't know what rifle to get. New, good ones seem to go for $1000+. I've been lurking used markets but being left handed is making it a bit harder to find.
