I think your technique is slick and it gives you peace of mind, and anyone that crafts their own ammo should recognize the value in knowing that you did your level best to make great ammo. I mean, I can certainly say this for myself. Pride in what I make shows up in my results. I have confidence in my ammo that translates to great shooting and I'm sure of that.

So don't discount your process that has worked.

With that out of the way, I also decided about 28 years ago that it was preposterous for me to clean primer pockets and so I will not EVER do that nonsense again, but my handloads are still absolutely fantastic.

Along those lines... I think that removing of those bits of impurity probably isn't much benefit and if I were in your position, I wouldn't do it. The tiny occasional brass bits will be blown out with each shot. If you have any "left in the bore" it would only be from the last round fired and none previous. And the flakes of sealant are getting beyond incinerated I'm sure.

That doesn't mean you should stop, this is simply how it occurs to me.
