I think there are far more doubles in use today, than a few years ago! Both by PH, and client hunters, where DG is on the ticket. Back in the early 90s one seldom saw a double in the hands of either a pro, or client, but that has changed drasticlly, in the last couple of years. On safaris where buffalo, and elephant are on license I would say a full 50% of the client hunters now have doubles. I predict, that in the near future you will see many more first timers to dg hunting with doubles, because of the flood of reasonably priced doubles in some good chamberings, anlong with the recent availability of factory ammo, and componants.
