zwego, I have your gun.
For the second time I have had Art of Art's Gun and Sport Shop in Hillsboro MO. mate a set of 30" BSS barrels to a BSS Sporter Frame. The finished product is a 30 inch Sporter that balances at the hingepin, oil finished english stock with semi-beavertail forend, single selective trigger, auto safety. DAC 1 5/8, DAH 2 5/8 and a LOP of 14 3/4 to a Kick-Eez pad. Wood is uncut and I've retained the Browning buttplate. Choked Full/Mod and just waiting for a set of Briley thinwalls.
I've been shooting it's twin at Skeet, S.C. and Continental Trap with such success that my buddies have suggested I sell all my other guns, that I had found my ultimate. I have also been shooting an original BSS 30 inch with a PG stock, mammouth beavertail forend and a blinding high gloss finish that's no slouch either.
It was said earlier that almost no side by side would/could stand up to thousands of rounds of heavy shooting. I beg to differ and offer up the Browning BSS side by side as a gun that can take it.
Art Issacson, a 25 year Browning gunnsmith has told me he feels the Brownings are dollar for dollar every bit as tough a gun as a Winchester 21. I own and shoot both and would have to agree.
