I have an opportunity to buy a Remingon Model 700 short action rifle chambered in 308 Winchester. It has a factory brown laminated stock and has been rebarreled with a Krieger 28" barrel. It has a jewel trigger and a 6.5-20 power Leupold tactical scope in Leupold tactical rings and bases.It also has been pillar bedded. Today I watched its current owner shoot two 10 shot groups that measured about 1.5" at 200 yards. Is this a good deal at $1,250 and could it be rechambered effectively in 300 WSM? Please let me know your opinions. Thanks
