My thoughts after owning at least one of each. All would shoot under sub 1" groups with proper load workup. Custom barrels are usually easier to break-in and clean up quicker when compared to the Savage or A&B. You would be surprised how many Savage barrels will shoot sub 0.5" groups along with the best custom barrels. I would buy another McGowen or Sin-Arms barrel witout reservation. And you can play with and cull 3 Savage factory barrels for the cost of a custom barrel.
