I haven't experienced the issues many of you seem to have had with rimless cartridges in a DR or, for that matter, in my single shots which normally operate the same way. Sure, both the DR and singles were built from the outset to use a rimmed cartridge, but they have both been adopted to rimless cartridges with little fuss. Of course, the extractor has to be set properly on any rimless to do the job properly, but if that is done right, you should not experience any problems.

There are a substantial number of high end British DRs chambered for rimless cartridges, including the 375 H&H which have continued to function quite well despite their age. Many modern doubles are chambered for a variety of rimless cartridges, including 30-06 and, again with proper design and fit, work just fine. Granted with a dangerous game rifle, I would prefer the last possible assurance of function and would want a rimmed cartridge, but other than that, the availability and cost of a rimless would be a factor to consider as well.

So? There is no 'correct' choice and you can select whatever floats your boat. Dave
