I had a 9.3 for about 4 years (until college tuition reared its ugly head). Mine was not a Utility grade nor the higher grade. I ordered mine based on a UGEX with several upgrades; cheepiece, steel grip cap and long tang trigger guard, claw mounts installed with 1.5x6 S&B scope. regulated with scope a sprimary sighting system with Norma 232 gr (I think its that, not the 286 gr) with swivels attached and Decelerator pad added. Gun was ordered with standard wood and what the put on it was fantastic, definitely much nicer than standard but they didnt charge a nickel more for it. Rifle shot two pair into 1.5" at 100 yards with boring consistency. The Sellier & Bellot load would shoot two bullets in a single hole from each barrel but about 5 inches apart at 100 yards. No they didnt cross.
Only drawback was thew rifle was fairly heavy with the scope and mounts but it was such a nice looking rifle i lokked past that aspect.

One note for 9.3 x 74 shooters. I had a chamber insert made to fire the 9mm Markarov pistol cartridge. This rifle would shoot 2 pair (2 from each barrel) into a ragged hole at 25 yards about 6 inches low from the point of aim but dead nuts for windage. Sounded like an air rifle. Very inexpensive practice for 9.3x74.

if I could buy a double rifle right now I would buy another Chapuis.

Note: There was (may still be ) another gunmaker in France named Chapuis that makes double rifles of a different pattern than the known Chapuis. That may explain the one posters question about his not having split lumps like the current Chapuis have.
