I'm not a "bullet " shooter so I can't help you there…
As far as patch lube, there's more concoctions out there than you can shake a stick at…

Some work as advertised, some don't.
In my personal experience , a lot depends on the type shooting you're doing …
Hunting or target shooting , 1 shot vs 25.
Weather & humidity levels are part of the equation as well.
Some lubes just don't do well in cold weather and others don't do well in the heat.
Like Wobblyshot said, shooting 25 times a day a Man don't want too have to stop a work on your gun every time the next target comes available.
I have used several different lubes or homemade concoctions over the years and have finally settled on 1-cup Murphy Oil Soap, 1- cup of Mr. Clean .(green)
Pour thie two items in a 64 oz bottle and top off with the cheap blue windshield washer fluid.
I then transfer it into a smaller container in my cleaning kit.
It makes a green concoction that cuts powder residue as good as anything if tried.
I use it for both shooting patch lube and cleaning solution.
My patches are pre dampened and kept in a small container in my pack or bag.
So basically I'm wiping my bore with the patch as I load each shot.
For hunting when my gun might be loaded for days, I use EVOO.
With a pinch of wasp nest between the patch & powder.
Here's a couple items I've used over the years including good ole spit..and Bear grease.
All of which worked well.
Lots of choices out there, just find what works best for your situation.
