I have the opportunity to purchase a modern manufacture drilling (Blaser) which has two rifle barrels and a shotgun barrel. However, one of the rifle barrels is chambered for 6.5X55 Swedish Mauser which is not a rimed cartridge. This cartridge is quite effective on big game but I am not sure it is suitable for use in a drilling.

Dos anyone here own a Blaser D99 drilling? How well does the extractor work? If it is chambered for a rimless cartridge, how do you load it? Just drop the round in? Do you need to make sure the extractor snaps over the groove?
