Something to keep in mind too, is the bulk of folk buy a DR to go to Africa with, and hunt the Big 5, so, a lot of the discussion is based on that application, or they want to shoot the bigbore old NE cartridges in them. Dry firing old doubles or bolts and breaking pins was a fairly common issue due to the way they did the interface of the pin and receiver, so they say, they claim it has been redesigned and rectified over the last 50-75 yrs or so, and write it off as not being an issue on newer guns. Haven't really seen that discussed much on any newer guns. Easy enough to build a round for dry firing that probably won't result in broken pins, did that for my 30R.. My Valmet o/u with SST used to fire on one bbl only, if you didn't lube the bbl switching anvil gizmo in it, it'd let you know by way of doing that, had to pull the trigger assy to get at it, did that on the hood of my truck a couple of times.
Really the only DR's I'd absolutely avoid are the "dremel tool" Sabatti's from about 15 yrs ago and back probably 10 yrs, Cabelas imported a batch that had to be re-regulated, the importer did it with a Dremel on the muzzle, some worked OK, bulk didn't. Think it was JJ Perrodeau in Texas had a method to fix that for a flat price, if it wasn't hime, he knows who did it. Some interesting discussions on that around at the time.
Have heard of a few Merkel 140's breaking triggers, haven't seen a good definition of how/why it happened, also lots of discussion of people doubling them, predominantly seemed to be the operator.
If you want to read some interesting stuff, do a Google search for "MacD37 on Accurate Reloading" , can likely change that to Africa Hunting as well, pretty sure he posted on there a lot too, it'll lead you to lots of discussions about DR's, and some other knowledgeable folk who chimed in on them.
