About ten years ago, Steve Bodio ordered from me a Bruchet slug gun, in 12 gauge. He bought the gun specifically for his trips to Mongolia, to eliminate the need for several guns. It was regulated to 60 yards with Federal slugs(customer's choice) and produced a 1 1/2" inch group that looked like a pair of eyes looking back at you from the target, at that range, and would have been useful to about 100 yards, if your game was on that day. It was not rifled, and was choked IC and MOD, to use birdshot with the rear sight folded down. He had his choice of stock, and he chose a semi-pistol grip with a cheek piece, and the traditional Darne sling. He would hunt big game in the morning, fold down the sight, remove the sling, and shoot birds in the afternoon, and he didn't need more than one gun in Mongolia. All was well.
The gun was featured in the DGJ, and was, near as I can tell, a far better all around choice than a rifled RBL in 20 would be for both big game, and birds. It was the only specific slug gun I ever sold.
I can't figure out all the excitement. It's been done, better, already.
Best,
Ted
