I just my got my Dad’s Sako L57244 Ackley back after years. I’ve got some questions I need help with. 1. is this a factory barrel? I was told it might be an aftermarket Douglas barrel cut down to about 19-1/2 inches. I sent pictures of markings/stamping on the barrel. I was told the barrel might be wore out and loose on accuracy. If it is bad should I buy a new barrel? And what calibers would be best to change to that would work with the 244 bolt? I’ve been told 6.5x55 Swedish would be a great fit. Or, would a re-bore of the old barrel be a better idea? If I redo the the old barrel would you change the caliber from the 244 Ackley? I would like to hear your ideas. Thanks, Mike.
