I have had a Chapuis Utility Grade SxS in 9,3x74R for about 6.5 years. I bought it at Chaddicks. It is color case hardened. The only difference between a $5000 Chapuis and a $20,000 Chapuis is the engraving and the wood, the mechanics are the same. Some models can be had as an extractor or an ejector. All SxS Chapuis have the double parallel under lug locking system. Under lugs are not the same as the locking bolt.
The Chapuis has a very wide locking bolt.
I have shot several thousand rounds through my 9,3.
I have hunted with it in Texas, Montana, Idaho, Canada, and Africa. I have 2 scopes in QD rings sighted in and ready to go. It shoots very well, from field positions I can shoot it on game as well as any bolt action. I have taken game with it out to a little past 300 yards.
It is my favorite hunting rifle under 40 cal.
I can highly recommend it.
