Can't answer some of your questions, but RF's tend to be individuals, be it rifle or handgun. Ruger has a well-deserved long-standing reputation for good products, so assume yours is one. Since you have already determined at least two brands of ammunition that don't perform well when plinking but you like how it shoots with Aquila, that's where you should focus and see if there is one particular Aquila loading that performs better than the others in your revolver.
I'd suggest you start with a clean gun, shoot a couple of cylinders to 'season' the bbl., but note where the first shot went [I think it important to know where that first shot goes from a clean bbl. w/a given type of ammo or load] and then began your 'testing'. Unless you are using something like a Ransom Rest, it's pretty much empirical and involves more than just good light. Many a competition shooter has noted the negative effects of caffeine or being tired or even distracted by life in general, so you want to avoid those things for best results, if you are not using a solid mechanical rest.
Just some thots, perhaps something of value to you.
Good shooting, regardless.
