+1 for Call of Juarez Gunslinger great little shooter with a sense of humour & some really good gunplay, well worth picking up!
Singularity, great (and challenging) shooter with a fantastic story.
Probably a bit much RPG stuff but give Borderlands 2 a shot. Lots of shooting, some sniping too
I especially like the sniper sections
BL2 is fairly heavy on the RPG elements, though. And while not purely open world, is the next closest thing.I enjoyed the gunplay in Borderlands 2.
The Game of the Year edition is knocking around at the mo @ around £7...
Sniper Elite 3?

Not really sure that's what the OP is looking for.
Instant Gaming has the Metro Redux bundle for just over a fiver. I haven't played Last Light yet, but I really enjoyed Metro 2033.
I would vote for the Metro series if you haven't played them yet. Both are awesome.
F.E.A.R is brutal and you'll feel like a bad ass mofo blowing people to bits and doing ninja kicks into skulls.
Sniper Elite 3?
