The key point being missed here in the discussion of style prefs., DR vs. bolt is that of having the gun stocked so that it naturally shoots where one is looking. You want the FIRST shot to find home. Talk of quick second shots w/big bore rifles of any kind is not quick.. due to recoil, but it is likely quicker in a DR than most bolt rifles.. unless one is using a Blaser or Kreighoff or one of the more modern bolt guns of that very fast feeding nature.
Its one of the big difs. w/American custom rifle stock makers, their instinctive mastering of classic lines w/shootable [meaning handles like a well made shotgun] dimensions vs. the average store bought bolt action that requires some funky and useless scope/rings/mount and will most likely never be shot well off-hand or w/the iron sights provided, but works well enough when shot from a blind or off a rest of some nature.
The factor of being able to be brought into play quickly & shot instinctively and accurately and having a second shot, when necessary, is whot brought the DR its favored status, IMHO.
Think about it, a SxS shotgun w/double triggers & hammers was/is nothing more than two independent shotguns sharing a common butt stock & forearm. Safety, as such, when applied to a DR is solely from that same redundancy.
Hey, the thread was already adrift, so thot I'd add my two cents en passant;-) I've no pachyderms in this ring.
