I have to respectfully disagree with the last poster, I have a couple of factory Savage barrels that are honest .3 shooters reguardless of how they look down the bore. I also have a few different custom barrels that are no better than the stock ones, and they are either select or match grade with lots of load work up.
The only one that is better by far is a Criterian 243 match bull barrel that is a .165 average size group that is on a PTA with custom stock( Shehane $$$ ) with Kelby bases and rings and a T36 Weaver. Unless you are willing to spend $3000.00 on a Savage just buy the LRP or build what you want and shoot to your hearts content or the barrel wears out then change.
