Again, I hate using the adverb "most" when talking about firearms, but I have to agree that if there is such an animal as "the MOST reliable" type of gun it would have to be a break action. The fewer moving parts the better. I know quite a few guys in the Double Rifle Shooters Society, and they seem to be quite proud of the accuracy of their doubles. Are they the "most accurate"? I doubt it, but again, I don't have any experience with them.
