I have yet to meet a BFR that won't shoot with or better than an FA. The fit and finish doesn't compare, but there's a lot to like about a BFR as a true working gun. Keep in mind that they are put together correctly and they use Badger barrels. Plus, you can safely carry it with a full cylinder. My .454 FA shoots well, but so do my "lesser" guns.

Just to be clear, I have examples of both of the guns mentioned here, and they both have their merits, but for a true reliable field gun, the BFR is one tough act to beat.
