I read your post right after breakfast, but did not have time to reply before leaving for FLG's shop.
Anybody who recommends doing RWR all the time must be trying to slow down his competition.
And trying to set them up for procedurals. I agree with RickB, learn the TR and forget the RWR. You can be required to do a TR, or you can have a choice between TR and RWR, or you can do "any IDPA legal reload", to include TR, RWR, or slidelock. But an RWR is never required. Not that I have seen, anyway. So why bother with it? In a few instances it can save you a *little* time but I don't think it is worth the effort of making the decision on the clock. But then I am not a Master Class shooter.
Surely if you can remember how the gun operates you can remember when to do a Tac Load or a slidelock reload.
It is even simpler for SSR. As you say, the Classifier (and many CoFs) call for a TR after six shots; no change in operation of the revolver is called for. If a TR is called for after less than six shots, you can do the Rulebook FAQ reload and "stuff the whole mess in your pocket." then reach for a speedloader. What I call the "baby with the bathwater" reload.
You can, of course, learn one of the old standard revolver Tac Load techniques. The usual one is:
Open cylinder, muzzle down.
Short stroke ejector rod and release.
Fired cases, being light and expanded will stay partly extracted, live rounds will drop back in their chambers.
Pluck out the protruding empties and replace them with individual rounds from Speedstrip, belt loop, or pouch.
Close cylinder and resume firing or ready position.
That works pretty well with one or two shots fired. More, and the plucking and replacing gets involved and slow.
I worked with what I called the "modified baby with the bathwater" method.
Open cylinder, position hand behind cylinder.
Raise muzzle, do NOT stroke ejector rod.
Catch live rounds as they fall out. Fired cases, being light and expanded will stay in their chambers.
Put live rounds in pocket, draw speedloader, stroke ejector rod HARD, let empties fly.
Reload with speedloader.
Close cylinder and resume firing or ready position.
I practiced that one for a while. It seemed to work pretty well, but I could not see that it had any effect on the CoFs I was shooting - including the Nationals - and gave up on it. Shortly after that I went back to CDP with .45 auto.
