Re: Rimfire across course match ?
I've only ever heard of it being used for NRA High-Power shooters. It's at 200, 300, and 600 yards (IIRC) in the three positions: offhand, sitting, and prone. Beyond that I haven't the foggiest clue about it. And especially not for rimfire; this is the first time I've ever heard of it referred to as a rimfire match. Does a range near you offer this match?
