The Browning T bolt is "half" left hand, I think Ruger has a LH model now, you can still find a CZ 452, if you can live with the assbackwardssafety.
I have an LH Anschutz that I like a lot, it was more money, but everything is where it is suppose to be on it and it's very accurate!
My all time fav LH 22, is a NULA that Melvin Forbes made for me! He made it the way I always wanted a 22 to be and as far as I'm concerned, it's the best of the best! Mel builds one damfinerifle!!
