Nice pictures in the snow.
I happen to own and shoot a Jonathon Browning in .50 cal. They
come in .54 as well. Mine happens to carry brass furniture while
others come in a brownish finish. The fit and finish and walnut
quality are first rate on the JBMR. They can be a tad pricey so you
need to have patience to find a correctly priced one.
