I have personally witnessed a chapuis 375 H&H fail to extract a fired case when hunting big game (factory ammo) which made me a little tense. A rimless cartridge would not be my first choice in a double rifle, a rimmed cartridge has to be more reliable in the field......The rifle was near brand new and had not been monkied with.

I too would go for a Heym, I know them to be very reliable. The Chapuis feel nice in the hand for the price. I have spoken to alot of owners of Heyms, including a few PH's and have heard nothing but praise.

Just my two cents worth.............
