I am considering converting a pre 64 FWT to 9.3x62. I like 24" barrels, They seem to balance best for me, but am looking at doing a 22" barrel on this one. I would like the rifle to be no more than 9 lbs. all up with scope and mounts. I am looking at a Leupold 2.5-8 that weights 11.4 oz. or no more than 16 oz. for something else. Wood stock currently. What size barrel would be good for this build in this caliber?
