OK, I'll bite.Just a couple replies:
#1: The transfer bar is another thing to move during the trigger pull. It is linked to the trigger, kind of like the series 80 linkage on a 1911. You're probably right that modern sears are cut for heavier pulls, but I can't recall ever testing a New Model that had a better trigger than an Old Model. Usually by considerable margin. That transfer bar is always there and always has to get moved as part of the trigger pull. It has inertia that is never going away.
#2: The Plum does look good, although I was referring to the polish. And today's bluing is terrible. There's almost no polish on the metal!
#3: I would NEVER load a single action revolver that way. When you lower the hammer right near the half cock notch, firstly you have a chance of breaking it off. I would always go to full cock prior to lowering. Secondly, when you lower the hammer in between notches, your bolt is grinding into the cylinder between the notches! The cylinder is unlocked and you're effectively locking it with your firing pin. With 357 models there's a lot of space between rims and a lot of opportunity for the cylinder to move between rims! You'll score a nice line into your unlocked cylinder with the bolt! You probably also aren't doing any favors to your firing pin with even a little rotational torque. If you have a molded holster (with fluted cylinder), your gun won't fit anymore because the cylinder is now out of alignment from where it is when it is locked.
Bottom line: Don't do this. This is silly. Load 5 like they have since 1873. Are you using your Ruger Blackhawk for self defense anyway? Five should be just fine for silhouettes, hunting, plinking, etc. I doubt Ruger ever referred to this method in their literature. They simply advise loading 5 with an Old Model. If you absolutely must load six, by all means just get a New Model. Your gun should always be carried with the cylinder locked normally by the bolt, not with the firing pin!
#4: The four clicks are indeed cool, but I agree, they are just cosmetic. The feature that I was referring to is the indexing detents between chambers while loading. With the new model, unfortunately, they are gone. When you open the gate, the cylinder just spins freely without the detent clicks to align the chambers like the SAA.
#5: Ruger Old Models (And Colt SAAs) are just as safe, if not safer. You only load five so there are no safety issues whatsoever. If you cowboy load, there's not even a worry with the "thumb slip" because your thumb would slip the hammer down on an empty chamber.
Both models are great but the Old Models are special. A 4 5/8s" Flattop from the 50s is superb. You just can't get that intangible "something" from a new one. Who cares about a 6th round? That's like lamenting the fact that a 1962 Ferrari 250 GTO doesn't have cruise control. There's a reason that the Old Models are much more desirable and expensive today.
What is this bolt you state is dragging on the cylinder?
I find no reference to a "bolt" in any parts list for either the NM or OM.
