DDouble, what solids are you planning on useing in your Chapuis? Chapuis will not warranty the rifle if you use mono-metel solids in your rifle! It seems there was a guy on AR,that used Barnes Super Solids, (Monolithic) and his barrels seperated from the ribs, twice! Chapuis fixed the rifle, then it did it again, and they began to ask questions. When they found out he had been useing monolithic solids, they fixed the rifle, and told him he was on his own, if he used the monolithics in this or another Chapuis double rifle! Woodlieghs are OK, and IMO the North Fork cps, and fps are useable in any double rifle because of their design, but Chapuis may not see it that way!
