Hi,I'd like to buy a 6.5X55 but no one makes a LH,nor do I think anyone is going to come out with on,though I've heard that CZ will come out with a LH but again I doubt in 6.5.Does anyone know the twist in the Ruger and the CZ,I'm looking for a fast twist as I'd like to shoot heavy bullets.Any toughts on the good and bad of both rifles?Thanks.
