My Pro Hunter was in an odd one, 6.5X57 (not a typo) one of the most accurate rifles I have owned. Mine if I remember right was a 23.4" barrel. They are a bit odd, but form, fit, and function is outstanding. 20" would be handier, but lose a bit of velocity. Daughter learned to shoot with it and I gave it her when she got married. Still trying to replace it..
